| Abstract: | The double wishbone suspension stiffness was calculated by using the virtual work principle,the vector algebra and tensor of finite rotation methods,and the feasibility of mathematic calculation was verified by the software Adams.By the random vibration analysis method,parameters of dynamic tire load(DTL),suspension working space(SWS) and comfort performance were analyzed and the basic parameter of designed torsion bar was optimized,which decreased the displacement of the suspension and limitted the frequen... |
