Abstract ：
The temperature field of tires has a significant impact on the cracking aging and service life of tires. Therefore, the finite element simulations of the temperature field of the mining tire were carried out in this paper. The temperatures of the key parts of the tire were measured with the thermocouple under real working conditions. The deviation between the results of the simulation and the measurement is 1.3%. In addition, the function among the maximum temperature, the velocity and sinking amount of the tire was fitted using the simulating results of the temperature field under the nine types of working conditions. Further, based on the response surface method, the structure of the 1# strap layer with high temperature of the tire was optimised by taking the width of the strap layer, the distribution density of the steel wire and the angle of the steel wire arrangement as the independent variables, and the maximum temperature of the tire under steady rolling as the response value. Finally, the results show that the maximum temperature of the optimised model decreases by 3.06 degrees C compared to the original model.

Abstract ：
Determination of tensile properties is essential for the design and strength assessment of structures. In this study, a modified small punch test (SPT), known as the single-stress small punch test (SS-SPT), was proposed to investigate the tensile properties of five ductile homogeneous materials, namely P91, Q245R, 316SS, 1045 steel, and 2024Al. The SS-SPT specimen was subjected to a single stress state when subjected to a punch force, similar to that of a uniaxial tensile test (UTT) specimen. Additionally, UTT and standard SPT were carried out to investigate the tensile properties of these materials. The thickness of failed standard SPT and SS-SPT specimens was measured using a scanning electron microscope (SEM) and the equivalent fracture strain was calculated. Correlation relationships between each type of SPT and UTT results were established. Experimental results indicated that both the SS-SPT and standard SPT demonstrated comparable accuracy in determining yield stress, ultimate tensile stress, and tensile elongation. However, the SS-SPT exhibited greater accuracy than the standard SPT in determining fracture strain due to direct measurement of the thinnest thickness from the fracture in failed SS-SPT specimens.

Abstract ：
Coupled energy absorption effect between the aluminum foam and the thin-walled tube plays a significant role in the crushing process. Firstly, a composite structure filled with aluminum foam in a multi-cell conical tube is proposed. Secondly, the influence of structure parameters on coupled energy absorption is investigated. Thirdly, the energy absorption mechanism is analyzed. Additionally, the structure is subjected to multi-objective optimization. The results show that increasing structure parameters are beneficial to coupled energy absorption effect. In addition, there are SEA = 26.18 J/g and FP =86.22 kN for the optimal tube, which is superior to most existing aluminum foam-filled tubes.

Abstract ：
Inspired by the microstructure of the beetle's elytra, a new bionic polycellular tube protective structure based on the fractal principle was proposed in this paper, and its energy absorption characteristics were studied. Firstly, the typical microstructures of two-branch structure (type A), three-branch structure (type B) and mixed-branch structure (type C) of the beetle's elytra were extracted. Based on that, three types of the bionic multicellular thinwalled circular tube (BMTC) were designed, and the reliability of finite element models was verified by experiments. Secondly, the energy absorption characteristics and crushing mechanism of three groups of BMTCs were compared and analyzed by LS-DYNA software, and the analytical expression of mean crushing force (Fm) for BMTCs was established. The results show that the energy absorption structures of type B have better comprehensive energy absorption characteristics. Compared with the traditional ribbed structure, specific energy absorption (SEA) of BMTCs is increased by 36.75 %. In addition, when the central column is connected to the three ribs, the central column has the best deformation resistance. Moreover, the theoretical solutions matched well with the results of numerical simulation. Consequently, the research results provide inspiration for the design of energy absorption protection devices, and theoretical guidance for the analysis of energy absorption characteristics.

Abstract ：
Several methods have been developed to determine the axial creep properties of nuclear fuel cladding tubes. However, the anisotropic creep properties of nuclear fuel cladding tubes requires that their circumferential creep behaviour be evaluated as well. Nonetheless, this task remains extremely challenging owing to need to employ unaltered cylindrical cladding tube specimens directly and the general low accuracy of the methods developed for this purpose. The present work addresses these issues by developing a modified small punch creep test (SPCT). Equations are proposed to calculate the creep stress and strain of the modified SPCT. The accuracy of the equations is analysed using the finite element method. Finally, the methodology is applied to investigate the circumferential creep behaviour of an FeCrAl nuclear fuel cladding tube experimentally. These results clearly demonstrate that the modified SPCT is suitable for investigating the creep behaviour of irregularly shaped material specimens with anisotropic creep properties. Moreover, the semi -cylindrical specimens employed in the modified SPCT also enable the effective fracture strain of the specimen to be easily determined.

Abstract ：
A novel weight sensor based on the Michelson interferometer is proposed in this study to meet the demands of complex environments. The sensor uses a dual-beam type elastic element, optimized to enhance its sensitivity. Its deformation under load is sensed by a broadband optical coherence displacement measurement system, which, in combination with the spectrum correction method, enables displacement sensing down to sub-nanometer res-olution. An optical interferometric weight sensor with a rated load of 6 kg is fabricated under laboratory con-ditions, and its performance is verified experimentally. The proposed weight sensor demonstrates good stability and achieves a sensitivity of 146.814 mu m/kg, theoretical resolution of 0.004 g, nonlinearity error of 0.034%, maximum repeatability error of 0.036%, and maximum hysteresis error of 0.055%, with the relative error of the identification threshold not exceeding 0.1%. The proposed weighing method and sensor represent a significant improvement over other reported interferometer-type weight sensors.

Abstract ：
该文对活体螃蟹的运动和大螯运作进行观察研究与尺寸测量,而后通过仿生学原理设计出一种八足、两钳组成的仿生机械螃蟹.通过建模构造出机械螃蟹的外形,并通过运动仿真验证机械螃蟹运动的可行性.结果表明,蟹类横向运动与其身体结构相关,蟹的足部关节只能上下活动,导致其步足只能横向伸展或收缩,且八只步足紧密靠近,前后摆动容易干涉.相比前后行进,横向运动更加省力,受到的阻力更小,运动速度更快.蟹钳一部分固定、一部分运动,其夹取运动主要靠羽状肌肉的收缩实现,收缩长度短、拉力大.综合蟹类身体构造及其运动特性,其步足运动可由平面六杆机构模拟仿真;蟹钳运动可由双摇杆机构模拟仿真.对机械螃蟹进行类型综合和尺度综合,并进行运动仿真,使机械螃蟹能够模拟蟹类步足横向运动和夹取运动.

Abstract ：
The study of deadweight force standard machines (DWM) that operate over a wide range is at the leading edge and a hot spot in force metrology. Optimizing the combination method of the weight load has important theoretical significance for improving the stability and accuracy of DWMs. Firstly, the law of weight loading position on a pendulum relevant to the hanging system through dynamical theory and finite element methods was studied, likewise the minimum pendular degree caused by the loading on the upper end of the hanging system was determined. Then, a method for optimal combination of weights was presented and carried out using MATLAB software. A force transducer of 1000 kN was selected to test on a 2 MN DWM, and the results show that the method can effectively improve the repeatability and linearity. Finally, compared with two random combination methods, the repeatability deviation decreased by more than 50%, and the linear deviation by approximately 10%.
