Currently,the seat dynamic comfort is the research and application focus of automotive engineering.The seat dynamic character is a key factor for the vehicle ride comfort,but few theory study and engineering application are available.According to the passenger car seat vibration under actual operation condition,the seats are simplified to a cantilever beam physical model,and the seat of simplified structure are analyzed and validated by the mode theory,the engineering design guide of seat modal is proposed.At the same time,a reasonable and effective seat modal test method is proposed to model seat vibration characteristics,which can avoid the seat foam nonlinear problem.At last,according to the seat dynamic parameters,the paper puts forward the engineering scheme of the seat vibration under the rough road,and improves the vehicle dynamic comfort.
