摘要
分析了离心摆式DMF-CS减振器的结构,运用Lagrange原理建立了离心摆式DMF-CS减振器的运动微分方程,推导出离心摆固有频率的表达式,并发现其固有频率与所在飞轮的稳定转速成正比。利用该特性,合理调整离心摆的结构参数,可在理论上完全消除发动机点火频率引起的扭矩波动。同时,对影响离心摆隔振性能的因素进行了分析。
The differential equations of DMF-CS with pendulum-type absorber were established, the natural frequency of pendulum was computed, and the characteristics that the frequency was proportional with the rotate speed of the flywheel where the pendulum was installed was found. Using this characteristic, the vibration of engine fire frequency will be absolutely eliminated theoretically by adjusting the parameters of the centrifugal pendulum. The influencing factors of performance of vibration isolation were analyzed.
