Abstract:
A torque characteristics mathematics-mechanical model of dual mass flywheel is established. The torque characteristics curve which is consistent with the test results is 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 the friction characteristics into account in the simulation model. Moreover,by the wedging friction of the spring seats’ heads, the torque non-linearly increases on the condition of large torsion angle. Thus the requirements that low torque and small torsion angle should be flexible,high torque and large torsion angle should be of high counter torque are satisfied. Then the 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.
