履带车辆动力传动系统扭振的时域仿真研究

Study on Time Domain Simulation of Torsional Vibration of Caterpillar's Powertrain

对某型履带车辆的动力传动系统扭振进行了仿真建模。针对动力传动系统中具有非线性特征的液力变矩器和盖斯林格联轴器等部件,建立了相应的非线性时域仿真模型,同时建立了发动机激励模型。将系统仿真得到的时域结果进行分析,并与实验数据进行了验证比较,仿真结果与实验数据较吻合。

The simulation model of a kind of caterpillar＇s powertrain had been built. And the non-linear characteristics of the hydraulic torque converter and the Geislinger coupling had been studied, time domain simulation model of the parts had been built. Then time domain excitation model of the engine had been built as well. At last the experiments on torsional vibration of the caterpillar＇s powertrain had been done, and the data of time domain simulation had been verified by the data of experiments.
