摘要
建立了双质量飞轮转矩特性数学力学模型,运用ADAMS软件对双质量飞轮进行动力学仿真分析,获得了与试验相吻合的转矩特性曲线,得出了考虑摩擦的仿真分析模型更能真实地反映双质量飞轮的转矩特性,并且可以增大转矩的结论;利用弹簧座头部的相互楔入摩擦作用,获得了大扭转角时转矩的非线性增加,实现了在低转矩小扭转角所具有的柔性、大扭转角时的高反抗转矩特性,使动力传动系统的一、二阶共振转速被完全有效地隔离在发动机的正常转速范围之外,达到了隔振设计的目标。
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.
