摘要: 大多数重型车辆均采用吊耳支架将悬挂系统与车架连接,为车架与悬挂系统的关键承载零件之一。基于拓扑优化理论及有限元方法,使用Hyperworks中 OptiStruct优化设计模块,对吊耳支架进行了拓扑优化,以在强度允许的前提下取得最佳的材料分布,使得质量最小。优化后进行了CAD模型重构,经与 原件的静强度和模态比较结果表明:新设计的零件较原零件质量降低34.07%,一阶模态提高6.81%,最大应力降低5.38%。此优化方法对车辆结构设计改进 具有实际工程指导意义。

Abstract: As one of key bearing parts of the suspension system and the frame, lug bracket was used by most heavy vehicles to connect the suspension system and the frame. Based on topology optimization theory and finite element method, Optistruct in Hyperworks was used to carry out the module design optimization, and the topology optimization of lug bracket was carried out, which was expected to obtain the optimal material distribution and a minimum mass in the premise of strength permit. After optimization, CAD model reconstruction was carried out. Compared with the static strength and modal of original, the results show that compared with the original parts, the quality of the new designed parts is reduced by 34.07%, the first order mode is improved by 6.81%, and the maximum stress is decreased by 5.38%. The proposed optimization method has practical engineering guidance for the improvement of vehicle structure design.
