摘　　要：结合虚拟样机技术和有限元分析技术,利用Pro/E、ADAMS以及ANSYS Workbench软件,建立多盘制动器弹子加压装置实体模型,对弹子加压装置进行动力学仿真,并对简化后模型进行有限元分析。根据在ADAMS软件中加压装置的运动仿真,得到制动弹子与弹子盘的接触受力情况,同时在ANSYS Workbench软件中对加压装置进行接触应力、应变分析,并结合Hertz接触理论计算加压装置Hertz接触模型的变形量大小。从分析结果中得出,Hertz接触理论并不完全适用于弹子加压装置的接触问题;由于受力较大,弹子槽与弹子接触表面易发生应力集中现象,反复加压会导致弹子槽磨损严重,发生磨损失效的现象,严重影响其加压效率和制动力的传递以及使用寿命。这为弹子槽表面强化工艺提供了理论依据。Based on Virtual Prototyping Technology（VPT） and Finite Element Method（FEM）, the marble-marble disk pressure mechanism is built using Pro/E, ADAMS and ANSYS Workbench software. Meanwhile the dynamic simulation and finite element analysis of pressure mechanism are carried out. Movement simulation of pressure mechanism is carried out using ADAMS software to obtain force distribution of the marble-marble disk. Then contact stress and strain are analyzed by ANSYS Workbench software, and the Hertz contact theory is used to solve the deformation of pressure mechanism Hertz contact model. The analysis results prove that Hertz contact theory is not fully applicable in the contact problem of the marble-marble disk pressure mechanism. The greater force causes stress concentration phenomenon on the contact surface between marble groove and marble. Repeated pressure can lead to serious wear of the marble groove, wear failure phenomenon, which seriously affects the compression efficiency, transmission of braking force and service life. The results can provide a theoretical basis for the marble groove and marble surface strengthening technology.
