Using ABAQUS software, the temperature field in the process of sliding friction of the dual steel plate of a new friction plate-conical friction plate was simulated and analyzed by the method of thermo-mechanical coupling. The distribution of heat flux density and the convective heat transfer on different surfaces of the dual steel were considered in the calculation. It is found that the highest temperature of the dual steel during sliding is inside the tapered groove. The temperature inside and outside of the tapered groove is distributed in a low-high-low state, that is, the temperature at the bottom of the tapered groove and the top of the groove is higher than the middle position The temperature gradient of the radial node gradually becomes larger with the passage of time; the temperature distribution of the entire dual steel plate shows a symmetrical trend. Introduction Clutch is an important transmission device in mechanical engineering. Its main function is to achieve smooth and efficient engagement and disengagement of the master and slave axes in a short time. Friction plate is the main component in the composition of the clutch driven plate. In the sliding state, the friction surface produces high temperature, which has a great impact on the clutch performance and strength. At present, many scholars at home and abroad have conducted a lot of research on the problem of heat production of friction pairs and achieved a series of research results. Such as: Luo Qingsheng, Han Baoling [1] applied thermal analysis theory and finite element method to study the temperature distribution of automotive friction plate; Yang Yang, He Qiang [2] through COMSOL thermal analysis of the torque clutch friction plate, simulation The temperature distribution of the friction plate is derived from the transient temperature field of the friction plate at different times during the joining process; Chen Guojin et al. [3] used the finite element technique to perform thermal-stress coupling analysis of the clutch friction plate; Zhang Jiayuan, Ding Puxian [4] et al. The ANSYS software uses a direct coupling method to simulate and analyze the temperature and stress fields of the friction plate during sliding and friction; Gao Xiaomin et al. [5] modeled and dynamically analyzed the engagement and disengagement process of the clutch and used it. “Permissible instantaneous temperature of frictional surface” is used as an index to measure the thermal load limit of friction plate; Zhu Maotao [6] analyzed the thermal structure of the friction plate during the start-up of the car, and the thermal deformation of the friction plate at the start of the car was obtained; Gao Xiang [7] et al. studied the temperature field and stress field distribution of clutch pressure plate. However, the friction plates they studied are all plane friction plates. At present, there is a new type of friction plate-cone friction plate in foreign countries. It has the advantages of large contact area, compact structure, and large torque transmission in the same space. In this paper, the thermo-mechanical coupling model of the dual steel sheet in the tapered friction plate is established to study the temperature distribution law of the dual steel plate. This provides a theoretical basis for the structural optimization of the new friction plate.
