The Vibration and Noise Study of Dry Double Clutch with Clutch Rigidity at Low Speed in Starting

[摘要] By establishing engine-clutch-vehicle body nonlinear dynamic, the nonlinear dynamic behavior of DDCT is studied with Clutch rigidity. The nonlinear dynamic behavior of the chaotic and bifurcation of the vibration of the clutch system is analyzed. The stability of the system is determined by the maximum Lyapunov index method; And combined with experimental study, the clutch noise and the vibration acceleration of the gearbox during the movement of the car are tested. It shows as follows, Reducing the Clutch stiffness can effectively reduce the noise and vibration acceleration. It is also provide a theoretical basis for solving the noise problem in the starting process.
