Abstract: The rear suspension of a light truck uses steel plate welded parts and rubber buffer blocks as suspension limiting devices, but the metal parts support is bulky and the height and size are fixed, and the same height support can not be fully adapted to different suspension systems, which is not beneficial to the parts status simplification and vehicle lightweight requirements. In this paper, composite materials are used to optimize the design of suspension bracket through structural improvement. The reliability of the optimized bracket is demonstrated based on HyperWorks finite element analysis and experimental verification, and the cost and weight of the bracket are reduced while the strength performance is satisfied.
