Investigation on Transient Vibro-impacts of Vehicle Driveline Based on Clearance and Friction Nonlinearity

doi:10.3901/JME.2021.10.050

Abstract

Abstract: Due to gear clearances of automotive driveline, transient vibro-impacts between gear teeth easily cause serious noise and vibration problem during fast engagement clutch, which decrease the vehicle sound quality. To analyze the transient vibro-impacts of driveline system excited by fast engagement of the clutch, a 9 degree-of-freedom lumped parameter dynamical model with piecewise linear clearance elements and nonlinear friction element for a rear-wheel-drive vehicle driveline system is established based on nonlinear theory of clearance and friction. The transient vibro-impact phenomena of the vehicle driveline excited by fast engagement of the clutch are numerically simulated. The plane phase reveals the phenomenon of multiple impacts and rebounds of the gear teeth in each transient impact, and shows the relationship between the relative contact deformation of the gear teeth and the relative angular velocity. Compared to axle clearance element, the transmission clearance element produces the largest transient impact force and elastic potential energy. During speed synchronization of the flywheel and clutch, the friction torque and Stick-Slip phenomenon between flywheel and clutch plate with different normal force are analyzed. Compared to the widely used friction model based on Karnoop friction theory, the numerical friction model established in this paper can better simulate the driveline vibro-impact caused by speed synchronization and the friction torque between flywheel and clutch plate during clutch engagement. The numerical results are verified by the vehicle tests.
