基于Matlab的后桥辅助驱动系统刚体模态分析及优化

Analysis and Optimization of Rigid-body Modal of Rear Axle Auxiliary Drive System based on Matlab

建立了后桥辅助驱动系统的6自由度振动模型,利用Matlab编写了刚体模态和解耦率计算程序,验证了其准确性,最后通过衬套刚度优化了刚体模态分布和解耦率。

Six degree vibration model of rear axle auxiliary drive system is established. A rigid body modal and decoupling rate calculation program is written by Matlab, and the accuracy of the pro- gram is validated. At last, the rigid body modal and decoupling rate is optimized.
