Abstract
In order to solve the problem of dual clutch transmission(DCT) gearbox rattle, the damping performance of DCT clutch micro-slip control is studied. A nonlinear dynamic model of the transmission system is established considering the hysteresis characteristics of the torsional damper, the dynamic friction factors of the clutch friction plate and the micro-slip double closed-loop control system. The effectiveness of the clutch micro-slip control model is verified by comparing the difference value between the target and the actual slip amount. Analyzed the influence of clutch friction plate dynamic friction factor and sliding amount on the clutch micro-slip control damping performance, and on this basis, discussed the damping performance of DCT clutch micro-slip control under acceleration condition. The vehicle road environment torsional vibration and gear rattle test of dual-mass flywheel with and without clutch micro-slip control are tested on under the same experimental conditions. The clutch micro-slip control on transmission system torsional vibration attenuation and improvement effect of gear rattle is analyzed through tests. and compared with the simulation results. The results show that the simulation results are basically consistent with the experimental results, which verifies the effectiveness of the simulation model and the attenuation effect of clutch micro-slip control on gear rattle. It has guiding significance for solving practical engineering problems.
