摘要
基于扩展的传递矩阵法建立了车辆动力传动系无分支系统和有分支系统的统一数学模型,利用Matlab平台编制了车辆传动系扭转振动分析软件。给出了求解有分支系统和无分支系统自由振动和强迫振动的关键技术。详细描述了利用扩展的传递矩阵法求解有分支系统和无分支系统动力学特性的统一数值解法。最后以某车辆动力传动系为例进行了计算,结果表明程序稳定、高效。
The united computation model of unbranched system and branched system has been built based on the expanded transfer matrix, which can be used to analyse the torsional vibration of vehicle driveline. Making use of the platform in Matlab, the analysis software has been built. The key technologies of free vibration and forced vibration analysis have been depicted. And the united numerical computation method for unbranched system and branched system has been depicted based on the expanded transfer matrix. Finally, the software has been tested with two instances of the driveline of one vehicle, and the results show that the software is effective and efficient.
