摘要
采用平均驱动自由度位移方法,对车身悬置的位置和数量进行优化设计,并针对优化设计前后车身悬置布置方案,分别对比分析了路面激励和发动机激励条件下的方向盘、座椅导轨和地板位置频率响应.结果表明:采用此优化设计方法进行车身悬置优化设计后,在路面激励和发动机激励条件下,车内振动响应均有不同程度的降低.
The average driving degree of freedom displacement method is used to optimize the position and quantity of body mount.The frequency response of steering wheel,seat guide rail and floor under road excitation and engine excitation are compared and analyzed for the body mount layout before and after the optimization design.The results show that:After the average driving degree of freedom displacement method is used to optimize the design of the vehicle body mount,under the condition of road excitation and engine excitation,the vehicle interior vibration response is reduced to some extent.
