Dynamic analysis of automotive clutch dampers
نویسندگان
چکیده
The torsional dynamic characteristics of an automotive clutch are simulated by ®ve lumped parameter linear or nonlinear models. Each nonlinear model includes visco-elastic and dry friction elements. Dynamic stiness and energy dissipation spectra clearly show excitation amplitude and frequency 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. # 2000 Elsevier Science Ltd.

متن کاملFinal Element Simulation of Blankholder's Lift-off in a Deep Drawing Tool Using Abaqus/Standard
In the deep drawing tools for forming car body parts, heavy blankholders are used to prevent buckling and wrinkling of the blank. During each press cycle, those large masses need to be lifted, raising thereby the structural dynamic load on the deep drawing tool and on the press. Therefore a detailed knowledge about the blankholder’s lift-off event is essential for an accurate and robust design ...
