基于随机振动分析法的双横臂悬架扭杆优化设计
Optimization design of torsion bar of double wishbone suspension based on random vibration analysis method
摘要
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 frequency of impacting the stop block. The result shows that it achieves better effect and supplies an accurate value for the general layout design.关键词
