基于MATLAB的混合电动车驱动系统扭振分析

Analysis on the Twisting Vibration of HEV Drive System based on MATLAB

混合电动车(HEV)是传统汽车与电动车相结合的产物,汽车工业发展的新趋势新方向。介绍了HEV的基本特点和驱动类型,根据HEV动力系统的基本框架,采用离散质量法和模态综合法对HEV动力传动系进行了扭振分析,采用MATLAB软件将各个零部件模块化,计算出柴油机子系统的各阶次的固有频率和振型。

HEV is a combination of HV and traditional vehicles which tend to be a new areas of vehicle industry. This paper gives a brief introduction of HEV and discusses the system of HEV based on two methods to analyze the twisting vibration of HEV drive system and uses MATLAB to achieve component modularization and to calculate the inherent frequency and main vibrate form of HEV subsystems.
