Research on the cross-scale mapping mechanism of friction mechanical behavior of metal rubber based on topological interference: Material level friction strengthening phenomenon EI

Abstract :

Based on the digital forming method of metal rubber, the Global point topology model (GPTM) reflecting the spatial characteristics is established to realize the mapping relationship between the index hardening characteristics of metal rubber and the wire turn motion behavior under the macro scale. The research shows that, with the reduction of the allowable wire turn motion space and the increase of the wire turn surface roughness, the internal multi-regional wire turns successively appear the spatial motion interference phenomenon, that is, the generation of the hard friction region, which is often the main cause of the metal rubber index hardening characteristics. At the same time, two kinds of materials, SUS-304 and Nichrome, are introduced to establish a microscopic model of metal surface roughness with fractal characteristics, aiming at realizing the research on the cross-scale friction mechanical behavior of metal rubber from the material level (microscopic level). The results show that HCP increases 97.6 % and 13.9 % respectively when the material is plastically deformed. While increasing the hardness and strength, the extrusion friction at the contact interface is increased, which affects the friction mechanical properties of metal rubber. The metal rubber (ASS-MR) made of 304 stainless steel entered the plastic phase earlier than that made of Cr20Ni80 (NI-MR) and increased the strength by phase change and rapidly entered the index hardening. The difference of mechanical behavior in the soft phase is closely related to the change of HCP on the contact surface of wire turn in the sliding process. Through the bottom-up trans-scale analysis method, the multi-level mapping relationship of metal rubber from the bottom material to the space structure and then to the nonlinear mechanical behavior is realized, which provides a new idea for exploring the basic performance and mechanism of this kind of micro-pore topology materials. © 2025 Elsevier Ltd

Abstract :

Entangled porous metallic pseudo-rubber (EPMPR) is formed by interlaced helical metal wires, and its unique structure can convert mechanical vibration energy into heat, providing significant damping effects. This study innovatively proposes a method for constructing the elastic hysteresis curve of EDMMR at the physical level, and decomposes and extracts the hysteresis curve using virtual manufacturing technology (VMT). Based on finite element numerical calculation nodes, this study constructs the stiffness curve of EPMPR's series-parallel structure, and considers the contact behavior of EPMPR, especially under high-temperature conditions, through dynamic evolution analysis of discretized numerical models of spatial contact behavior, further studying its damping hysteresis behavior. Specifically, this study also proposes for the first time and comprehensively analyzes the dynamic and static parameters of EPMPR under different temperatures and loads, providing in-depth insights into its mechanical behavior and energy dissipation mechanisms. Experimental results demonstrate that under the complex topology structure and thermomechanical coupling, the elastic hysteresis curve of EPMPR can accurately predict its damping characteristics under different high-temperature environments, providing a theoretical foundation for EPMPR's application in advanced equipment and structural extreme environments.

Abstract :

Superhydrophilic-underwater superoleophobic materials have received extensive attention in recent years due to their excellent performance in oil-water separation. However, they are still challenged by practical limitations. One of the main issues is the modification of traditional metal-based surfaces. These surfaces are typically modified through roughening and chemical treatment, but they still face significant challenges. Here, we report a metal rubber(MR) filtration material with exceptional superhydrophilic-underwater superoleophobic properties, fabricated through a synchronous process combining two-dimensional(2D) iron oxide sheets and zerodimensional(0D) silica nanospheres. This composite structure enhances surface wettability by integrating the dimensional effects of 2D and 0D components. This superwettable material, termed P-MRFS, incorporates a composite structure that enhances surface wettability by integrating the size effects of both 2D and 0D components. The P-MRFS material achieved a peak separation flux over 2500 L & sdot;m-2 & sdot;h-1 and up to 99.88% purity across various oil in water emulsions, including hexane, petroleum ether, dimethylbenzene, dichloroethane, and toluene, with a stable efficiency of 99.7% after 30 separation cycles. P-MRFS demonstrated durability under demanding conditions, maintaining over 99.5% separation efficiency after 48 hours in acidic, alkaline, and saline solutions and following 400 cm of abrasion under a 200 g load. Importantly, the study employed computational fluid dynamics(CFD) simulations to analyze the micro-scale mechanisms of emulsion separation, enabling realtime observation of droplet dynamics and revealing interactions within the multi-fiber structure that enhance separation efficiency. Overall, the P-MRFS material showed outstanding stability in corrosion and abrasion resistance, sustaining high emulsion separation performance even in complex environments. These findings suggest the material's high potential for future applications in oil-water separation, environmental protection, including crude oil recovery, and other industrial uses, underscoring its significant practical utility.

Abstract :

Acorrugated sandwich plate was prepared by metal rubber, and the macro and micro mechanical properties of the structure were studied by experiment and finite element respectively. In order to accelerate the calculation rate, the finite element equivalent model was established, and the influence of different material parameters on the mechanical properties of the structure was studied and verified by experiment. The results show that there are two stages under load:platform stage and compact stage. Compared with traditional corrugated sandwich board, the platform stage is longer and the energy absorption effect is improved. Combined with the test and the finite element, it is found that the reason for these two stages is that the ultimate load can cause the buckling deformation of the sandwich layer under the loading condition, thus reducing the internal voidage of the structure, and the structure is further loaded to the dense stage. The validity of the research results is verified by the comparison of the two, which provides guidance for the future design and application of metal rubber corrugated sandwich plate. © 2024 Cailiao Daobaoshe/ Materials Review.

Abstract :

As a key process in the rubber sealing molding, vulcanization has a significant impact on the performance of rubber sealing products. However, the rubber industry often adopts empirical vulcanization molding methods, lacking understanding of the evolution of vulcanization, making it difficult to theoretically guide the actual production process of rubber seals. In response to this weak link that restricts the improvement of rubber sealing quality, the paper conducted numerical simulation research on the vulcanization molding process of rubber seals. A transient simulation model for thermal-chemical coupling of rubber products was established based on an integral reaction kinetics model and a heat transfer control equation with variable physical parameters. Real time prediction of the time-varying temperature field and vulcanization degree field during the rubber product forming process was achieved, and the correctness of the model and solution method was verified through experiments. Furthermore, the vulcanization process of typical structural seals was simulated and analyzed, and the influence of mold temperature, rubber preheating temperature and temperature fluctuation behavior on the rubber seal vulcanization molding process was discussed. Finally, suggestions and references were provided for the actual vulcanization production of rubber seals. © 2024 Materials China. All rights reserved.

Abstract :

The surface of the TC11 titanium alloy is significantly strengthened through the ultrasonic tumbling process. The effect of ultrasonic tumbling process parameters on the microstructure and surface roughness of a titanium alloy using multiple techniques are investigated, including OM, white light interferometry, SEM, EDS, and XRD. The hardness, friction, and wear properties of the rolling surface are analyzed using a microhardness tester and a multifunctional friction-wear tester. The results indicate that the surface roughness of the titanium alloy decreases initially and then increases with an increase in rolling power, rolling times, static pressure, reduction, spindle speed, and feed rate. The lowest value is achieved with the following parameters: 660 W rolling power, 5 rolling times, static pressure of 0.20 MPa, reduction of 0.15 mm, spindle speed of 200 r·min−1, and feed rate of 0.10 mm·r−1. With an increase in power, the surface hardness of titanium alloy increases, which leads to a reduction in friction coefficient and wear loss. As the rolling times, static pressure, reduction, spindle speed, and feed rate increase, the surface hardness initially increases and then decreases. Meanwhile, the friction coefficient and wear loss tend to decrease initially and then increase. When the rolling power is set to 990 W, the rolling frequency is 5 times, the static pressure is 0.20 MPa, the reduction is 0.15 mm, the spindle speed is 200 r·min−1, and the feed rate is 0.10 mm·r−1, the hardness reaches its maximum value, while the friction coefficient and wear loss reach their minimum values. Response surface optimization was conducted to obtain the optimal process parameters, including a rolling power of 990 W, rolling frequency of 5 times, static pressure strength of 0.20 MPa, reduction of 0.15 mm, spindle speed of 198 r·min−1, and feed rate of 0.10 mm·r−1. Compared to the surface of the titanium alloy before rolling, the hardness increased by 36.4% from 337 HV to 461 HV, the surface roughness decreased by 89.9% from 1.88 μm to 0.19 μm, and the wear loss decreased by 83.3% from 0.60 mg to 0.10 mg. © 2024 Chinese Mechanical Engineering Society.

Abstract :

Here, aiming at the problem of significant performance degradation caused by environmental factors of polymer damping pads commonly used for vibration reduction in existing traction machines, taking engineering application requirements of elevator traction machine dampers as the guidance, after determining required damping components ' stiffnesses, vacuum infiltration technology was used to fill silicone rubber into metal rubber pores, form a coating, and develop a high-performance metal rubber - silicone rubber continuous interwoven phase composite damping material ( MR- SRC ) vibration damping material for resisting environmental impacts. Then, a finite element numerical model for elevator traction machine based on actual structure was established. Modal analyses were performed for elevator traction machine before and after installing MR-SRC shock absorber to determine natural frequencies and vibration modes of the overall system. Impact response analysis was performed for MR-SRC shock absorber, effects of different MR-SRC materials and impact loads on impact responses were compared to check MR-SRC shock absorber strength. Furthermore, based on the approximate equivalence of MR-SRC, theoretical calculations were performed for impact response of shock absorber system. It was shown that MR-SRC shock absorber with a metal rubber density of 1. 8 g/cm3 has the best damping effect. Finally, the fabricated MR-SRC vibration damper was installed in an actual elevator traction machine, acceleration and velocity changes of the elevator were measured during operation according to requirements of elevator vibration reduction national standard, the relevant characteristic parameters of elevator operation were calculated and checked. The results showed that MR-SRC vibration damper designed here can provide a new approach for safe and reliable operation of elevators. © 2024 Chinese Vibration Engineering Society.

Abstract :

The poor mechanical properties exhibited by pure Zn effectively prohibit its utilization as a viable material for biodegradable implants. Hence, the primary area of interest has been directed towards alloy design and process strategies of biodegradable Zn alloys. To this end, novel biodegradable Zn-xCu-xTi (Cu: x = 0.001 - 2.72 and Ti: x = 0.03 - 1.21) alloys were designed and fabricated using a gradient continuous casting method followed by homogenization and rolling. The fabricated samples were then investigated in terms of their microstructures, mechanical properties, and corrosion behavior. The results showed that the as -cast Zn-0.001Cu-0.037Ti and Zn1.50Cu-1.06Ti alloys possess better mechanical properties and corrosion resistance. The yield strength, elongation, and highest charge transfer resistance (Rct) of Zn-0.001Cu-0.037Ti were 137 MPa, 60 %, and 2227.9 Omega , respectively. On the other hand, the Zn-1.50Cu-1.06Ti alloy exhibited 250 MPa yield strength, 12.7.% elongation, and 11113.0 Omega Rct, respectively. Higher Cu and Ti content also led to larger second phases. However, as -hot rolled Zn-1.50Cu-1.06Ti alloy displayed better mechanical properties as compared to the Zn-0.001Cu-0.037Ti alloy due to a very fine nanocrystalline structure. Furthermore, the hot -rolled Zn-xCu-xTi alloys demonstrated superior corrosion resistance compared to their as -cast counterparts, as evidenced by the analysis of the potentiodynamic polarization and electrochemical impedance spectroscopy data. This improved corrosion resistance is attributed to the refined grain size, fractured second phases which reduce both the anode and cathode areas, and the formation of protective oxide layers. Lastly, the corrosion products primarily consisted of carbon, phosphorus, calcium, and oxygen, suggesting the presence of Zn(OH) 2 , carbonates, and phosphates.
