Here, aiming at problems of single frequency, multi frequency and stiffness and damping exceeding allowed ränge faced by applications of magnetorheological Vibration absorber in longitudinal Vibration control of propulsion shafting, a semi-aetive control method based on variable stiffness and variable damping magnetorheological Vibration absorber was proposed to realize frequency synchronization and damping optimization, and broaden Vibration reduction bandwidth of propulsion shafting. Firstly, the propulsion shafting-magnetorheological Vibration absorber coupled model was constructed and its dynamic equations were established to analyze longitudinal Vibration characteristics of propulsion shafting. Then, taking stiffness and damping optimal control criterion as the constraint and displacement zero-tracking of the controlled object as the control objective, an integral sliding mode Controller was designed, and Lyapunov stability analysis was performed. Furthermore, Vibration control Simulation was performed for propulsion shafting to analyze the semi-active Vibration absorption effect, and verify the effectiveness of integral sliding mode control. Finally, an experimental platform was built to conduct scaled-down Vibration absorption experiments. Experiments showed that this Vibration absorption method can make propulsion shafting quickly reach its steady State under different operating conditions, and effectively reduce the Vibration acceleration level within propulsion shafting excitation frequency ränge of 6. 0 -30. 0 Hz transmitted to thrust bearing base; This new Vibration absorption method can not only be expected to break through the bottleneck of propulsion shafting Vibration reduction under variable working conditions, but also enrich the theoretical basis of Vibration control field and provide common theoretical guidance for similar Vibration absorption problems. © 2025 Chinese Vibration Engineering Society.

Abstract ：
Nowadays, many scholars have been studied the normal force of MRF in the uniform magnetic field. However, the research on the normal force of MRF in the non-uniform magnetic field is relatively limited. The non-uniform magnetic field can cause the MRF to generate normal force of different sizes and directions to cope with different working conditions, thus the normal force generated in the non-uniform magnetic field require more attention. In this paper, a theoretical model of the normal force of MRF in the non-uniform magnetic field was developed based on the enhanced magnetic dipole model. The normal force of MRF within a unit area can be calculated based on this theoretical model. However, the magnetic induction intensity is different at different locations of the non-uniform magnetic field, which leads to the normal force generated by the MRF are not accurately calculated. Therefore, it is necessary to use COMSOL to establish the material model of the MCR-302 plate rheometer and MRF to verify the accuracy of the proposed model. Then a flat-plate rheometer was used to test the static normal force of the MRF in the non-uniform magnetic field. Finally, the simulation and experimental data were compared. The results show that the simulation result with the experimental data is a good agreement, which verifies the reliability of the theoretical model. The static normal force of the MRF increases with the increase of volume fraction and magnetic field intensity.

Abstract ：
Magnetorheological dampers (MRDs) are applied to hydraulic systems, which not only improve the underdamped characteristics of valve-controlled cylinder systems, but also help hydraulic actuators to resist high load impact. However, the high power density leads to the complexity of the internal flow channel of the damper, which seriously affects the output accuracy of the damping force. It can lead to the fact that existing dynamics models cannot accurately describe the hysteresis characteristics of the MRD. Therefore, this study proposes a simple and general dynamic model of MRD, which solves the problem that existing models are complex and difficult to invert. Firstly, the hydraulic damping actuator with the series MRD is taken as the research object. Based on the stress-strain hysteresis characteristics under the cyclic constitutive model, the hyperbolic tangent curve is reorganized and normalized. It can accurately describe the yield formation and yield dissipation stages of the hysteresis loop. Secondly, the relationship between the parameters of the dynamic model and the current is obtained according to the mechanical experimental data. Then the inverse model of the MRD is established by using the method of section-backstepping. Finally, in the static experiment, the mean absolute percentage error (MAPE) of the force at different velocity is less than 7.5%; in the dynamic experimental test, the MAPE of the force is 9.7%. The inverse dynamics model is verified to have high tracking performance under both static and dynamic forces. And it also indirectly confirms the effectiveness of the forward model.

Abstract ：
The internal noise sources of the bent-axis piston motor are close in distance. For example, the distance between the inlet and outlet of the motor valve plate is 38 mm, and the noise sources have the same frequency and multiple frequency phenomenon. The dense and complex noise sources in the bent-axis motor cause difficulties for the spectrum analysis method to accurately identify the same frequency and multiple frequency signals. The maximum resolution of traditional sound intensity measurement is 50 mm, which cannot meet the requirement of identification accuracy of motor internal noise source. Aiming at the problem that the traditional methods are difficult to identify the motor noise sources accurately, this paper proposed a sound intensity measurement method based on compressed sensing. The compressed sensing theory was applied to the high-precision reconstruction of sound intensity image to obtain the high-resolution sound intensity reconstruction image of the motor. Firstly, the noise radiation simulation of the bent-axis motor was carried out to obtain the characteristics of its external surface sound field. Then, based on the sound intensity image for the motor, a compressed sensing frame applied to the motor sound field was designed to obtain the sound intensity cloud image of the motor with high precision. Finally, the feasibility of the compressed sensing theory to improve the identification accuracy of motor noise source was verified by comparing the traditional acoustic intensity measurement with the compressed sensing acoustic intensity measurement. The results show that the identification scale of motor noise sources are improved from 70mm to 30mm by the sound intensity measurement method based on compressed sensing, which improves the accuracy of motor noise sources identification and realizes the high precision location of motor noise sources. © 2024 South China University of Technology.

Abstract ：
The current, electromagnetic force, and dynamic displacement of the high-speed on/off valve's (HSV) electromechanical converter under stable working cycle are significantly different from those under the initial movement cycle. This phenomenon determines whether the electromechanical converter can continue to operate stably, and it also leads to temperature rise and high energy consumption over long periods of time. Therefore, in this study, a high-precision model is proposed that can fully analyze the characteristics of the electromechanical converter under multiple motion cycles with the consideration of the effects of eddy current and hysteresis. First, the hysteresis loop of the material is tested, and the Jiles-Atherton hysteresis model is identified based on the test data and verified through experiments. Second, the fundamental reasons for the differences in current and electromagnetic forces between initial motion and stable motion are analyzed. On this basis, a new law of dynamic evolution of electromechanical converters under multiple motion cycles is discovered. Finally, the important influence of hysteresis characteristics and eddy current on the dynamic performance and energy loss of the electromechanical converter under multiple motion cycles is analyzed. The effects of frequency, voltage, and external resistance on the dynamic characteristics and energy loss of electromechanical converters have also been analyzed. The results indicate that as the voltage increases, the response time decreases, but the eddy current loss increases. An increase in external resistance will increase response time but reduce eddy current losses. This study can provide a theoretical basis for further improving the performance of electromechanical converters.

Abstract ：
When hydraulic-legged robots move under high loads on irregular ground, they are vulnerable to ground impacts. Vibration affects the motion performance of the robot and damages its mechanical structure. This study aims to improve the properties of vibration absorption and impact resistance of hydraulic-legged robots. Because the traditional MR damper (MRD) has small output in finite volume, a novel MRD with a multistage flow channel (MFC-MRD) can output a large damping force designed. First, an MRD prototype was designed for a mechanical leg's driving joint. Subsequently, the system is analyzed theoretically, and a semi-active control strategy is designed and simulated. Finally, the vibration and impact resistance of the prototype were tested. The experimental results show that in the signal tracking experiment, the maximum overshoot under semi-active control was reduced by 53.0%, and the settling time was reduced by 76.9% compared with the passive control. The impact test reduced the maximum displacement fluctuation by 41.09%, and the buffer time is only 0.24 s.

Abstract ：
A dynamic vibration absorber (DVA) using magnetorheological (MR) for synchronous stiffness and damping control is detailed in this study. The variable longitudinal vibration frequency of propulsion shafting, which is attributed to a broad spectrum of propeller speed fluctuations, necessitates effective vibration mitigation. Conventional DVAs suffer from limited tunability, which can lead to the failure of optimal resonance, narrowed vibration suppression bandwidth, and potential vibration exacerbation. Thus, a control criterion for optimizing the stiffness and damping parameters is proposed in this study. Firstly, a longitudinal vibration dynamic model for the propulsion shafting system is developed, to determine the acceleration transmissibility and resonance frequency points. Next, a magnetorheological vibration absorber (MRVA) is designed to encompass synchronous controlled stiffness and damping. The mechanical property evaluations and frequency shift tests confirm the absorber's capacity for variable stiffness and damping. A coupled dynamic model that integrates the propulsion shafting system and MRVA is established. A control criterion for the stiffness and damping has been formulated to accommodate the diverse working conditions. The results of the vibration reduction experiments substantiate the efficacy of the proposed control criterion, thus demonstrating the attenuation of acceleration amplitude above 37%, besides, up to 90% has been achieved at specific frequencies.

Abstract ：
Based on production practice, it is known that the mixing scraper is an important mechanical part that the planetary mixer directly contacts with the concrete. Its structural shape will directly affect the mixing effect of the mixer, and the inclination angle of the mixing scraper is one of the most important factors affecting the mixing efficiency of the mixer. In this paper, based on the discrete element numerical analysis method, a three-dimensional simulation model of the vertical axis planetary concrete mixer is established, and the concrete mixing process is simulated, and the inclination angle of the mixing scraper is optimized based on the simulation results. An automatic precast concrete mixing experiment platform was built, and the simulation results were verified experimentally. The research results show that the experimental data and the simulation results are very consistent, which verifies the accuracy of the discrete element dynamics simulation model. It can be seen from the simulation and experimental results that the mixing efficiency of the mixer is the highest when the inclination angle of the mixing blade is 45 degrees, and the number of collisions between different types of material particles in the mixing tank is the highest.

Abstract ：
As one of the most important mechanical parameters of magnetorheological fluids (MRF), the normal force has been studied by a large number of researchers using various experimental equipment and methods. However, it is difficult to reveal the effects of particle microstructure characteristics on the normal force of MRF by experimental methods, especially for such factor as the particle size distribution. To advance this research area, a numerical method for calculating the normal force of MRF is proposed in this study. The accuracy of the simulation model is verified with the experimental results measured by a plate-plate magnetorheometer. The results show that the simulated values agree well with the experimental data, which indicates the feasibility of calculating the normal force of MRF using numerical methods and provides a new research idea for a more intuitive and comprehensive analysis of the normal force characteristics of MRF. Besides, the simulated data show that the increase in magnetic field intensity and particle volume fraction will sufficiently enhance the normal force of MRF and improve the response time of MRF. For the MRF with the same particle volume fraction, a decline in the average particle diameter will increase the normal force. Moreover, increasing the dispersion of particle size of MRF particles can also improve its normal force.
