为寻找结构简单、性能优越的悬架结构ISD(Inerter Spring Damper),对储能元件、支撑元件及耗能元件按不同位置构建21种工程上可行的拓扑结构,建立通用动力学模型。以簧上质量加速度及轮胎动载为目标进行优化,获得每种结构的元件参数。有12种新型结构性能优于传统悬架,对典型结构分析表明,动力学建模与参数优化方法在ISD悬架设计中具有一般性、通用性。

A general method to design interter-spring-damper (ISD)suspension structures was introduced.Twenty-one kinds of new suspension structures feasible in engineering application were built by the method of locating energy storage elements,supporting elements and damper elements in different positions.The general dynamic model of these structures was built then.The optimization of acceleration of sprung mass and dynamic load on tyre was used to obtain the parameters of mechanical elements.By the comparison of the new and traditional suspensions,twelve kinds of new structures were proved to be more excellent.The analysis of typical structures indicates that the method based on dynamic model and parameter optimization is general and universal to design ISD suspension structures.
