Optimal design of a vehicle suspension based on a compliant mechanism

车辆悬架是由多个悬架臂、弹簧和阻尼器组成的典型连杆机构。为了减轻汽车悬架的重量和零件数量，提高其可靠性和设计灵活性，提出了一种基于柔性机构的汽车悬架，并提出了基于拓扑和形状优化的汽车悬架优化设计方法。利用该方法进行了实例研究，并制作了原型缩尺模型进行了试验。

A vehicle suspension consisting of several suspension arms, a spring and a dumper is a typical link mechanism. To reduce its weight and the number of parts and to increase its reliability and design flexibility, we proposed a completely new type of a vehicle suspension based on a compliant mechanism and developed its optimal design method based on topology and shape optimization. A case study was carried out using the proposed method and a prototype scale model was manufactured and tested.
