Dayamic analysis of automotive clutch dampers

摘要

The torsional dynamic characteristics fo an automotive clutch are simulated by five lumped parameter linear or nonlinear models. Each nonlinear model includes visco-elastic and dry friction elements. Dynmaic stiffness and energy dissipation spectra clearly show excitation amplitude and fequency dependent behavior. Also, dynamic hysteresis curves are predicted and analyzed. The proposed models compare well with limited experimental data. Finally, the utility of such models is illustrated via a transmission rattle simulation program.
