Research On Comprehensive Test Simulation Technology Of Vehicle Friction Clutch

Thesis combines with the fund project Design and Development of Clutch Components, in Changchun YiDong clutch manufactory. Attempting to find out comprehensive test simulation technology of vehicle friction-clutch in a systematically and scientific manner. Developed an automotive friction-clutch simulation-testing technology based on finite element method.In this thesis, I design the dimension parameters for DST180H8 clutch, which is going to be installed in the small car of Cherry-Auto Group. Using by CATIA software to carry out the three-dimensional modeling of the clutch. Based on ANSYS, completing the ultra-speed spin simulation test of the automobile clutch spider, clutch-assembly dynamics finite element simulation test, stable working state simulation test of clutch and clutch dynamic axial compression simulation test based on the LS-DYNA module. Getting the results of nodes' displacement and elements' von misses stress of clutch components, in order to find out the weak-points of these parts in different situation. Deal with the defects of clutch components, by optimization of parameters, to get the ideal design material parameters of components.The simulation results compare with the sample pieces of DST180H8 clutch of the actual test results shows: The simulation results with high precise, could be able to meet the engineering needs and provide theory foundation for physical dimension and technological parameter of clutch design.
