Calculation method of radial displacement in the engaging process of wet friction clutch

The radial vibration of the wet friction clutch has a certain influence on the engagement characteristics during the engagement process, and this influence cannot be ignored. This paper takes a variable speed configuration as the research object, establishing a six-degree-of-freedom equivalent bending-torsional vibration model of the variable speed transmission system, and studies the calculation method of the meridional displacement during the engagement process of the clutch. The Runge-Kutta method is used in this paper to solve the dynamic model and analyzes the relationship between the joint state and the radial vibration amplitude. The verified experiment is then conducted. Simulation and test results show the following: the clutch eccentric distance and the radial vibration amplitude, as well as the mass of the driven disc of the clutch and the radial vibration amplitude, all increase. The supporting rigidity of the clutch becomes large, the amplitude of radial vibration becomes small.
