汽车双质量飞轮转矩特性建模与仿真

he torque characteristics mathematics-mechanical model of the dual mass flywheel was established. The torque characteristics curve which was consistent with the test results was obtained by dynamics simulation analysis of the dual mass flywheel by using ADAMS. It is concluded that the work process of the dual mass flywheel can be more authentic and the torque can be increased greatly by taking into account of the friction characteristics in the simulation model. Moreover, it shows that the non-linear torque increases on the condition of large torsion angle. And the requirements that low torque and small torsion angle should be flexible, high torque and large torsion angle should be of high counter torque to meet the vibration isolation design goal that the driven system's first-order and second-order resonant speeds are beyond the normal speed of the engine can be achieved by the wedging friction of the spring seats' heads.
