Study on the Natural Performance of Automobile Power Train with Dual Mass Flywheel Damper

基于装备有离合器从动盘或扭振减振器和双质量飞轮式扭振减振器的汽车动力传动系,建立了扭振固有特性计算分析模型,采用广义Jacobi算法计算出了各扭振系统模型的固有特性和固有振型,并进行了临界转达和临界车速的计算分析,得出了双质量飞轮式扭振减振器对汽车动力传动系统扭振固有特性的影响特点.

In this pater, on the basis of automobile power train with clutch damper and dual Mass Flywheel Damper. The calculation and analysis models of system's natural performance are built,the natural frequency and natural vibration modeling of the torsion vibration systems are calculated by means of generalized Jacobi's method,and the calculations and analysis of the critical speed and critical velocity are carried out,then the influences on characteristic of the automobiled power train are obtained, this will have an important meaning for the calculation and analysis of the automobile power train,the theory basis is given for the designing of the dual mass flywheel.
