车辆动力传动系通用扭振模型的研究

Study on Torsional Vibration Model of the Powertrain of Vehicle

建立了车辆动力传动系的通用力学模型和数学模型 ,利用 Matlab强大的矩阵计算功能和 GUI函数编制了计算系统固有特性的软件 ,可对车辆动力传动系多自由度无分支轴系和分支轴系扭振模型进行计算 ,以某重型车辆动力传动系为算例进行了扭振计算 ,结果表明程序稳定。

A universal mechanics model and mathematics model were built to study the free torsional vibration of powertrain of vehicle in this paper. With the powerful functions for matrix calculation in Matlab, the program for calculating the free vibration was designed, written and tested. It can be used to calculate torsional vibration for the powertrain both without branches and with branches. At last, the program is tested with two instances of the powertrain of one track vehicle, the results show the program was interface-friendly, effective and efficient.
