摘　　要：为提高赛车立柱的强度,延长使用寿命。基于多体动力学方法,运用VI-GRADE的VI-CarRealTime模块建立整车动力学模型进行动力学仿真,提取轮胎的极限载荷。通过搭建力学模型,计算立柱静力学分析所需的边界条件。根据SIMP变密度法,利用Ansys Topology Optimization对立柱进行拓扑优化。结果表明:优化后的立柱,其应力相比旧方案下降49.02%,质量降低4.71%。In order to improve the strength of racing car upright and prolong its service life.Based on the multi-body dynamics method,the VI-CarRealTime module of VI-GRADE was used to establish vehicle dynamics model for dynamic simulation and extract the ultimate load of tire.The boundary conditions for static analysis of upright were calculated by building a mechanical model.According to the SIMP variable density method,the Ansys Topology Optimization was used to optimize upright.The results show that the stress and quality of optimized upright are reduced by 49.02%and 4.71%compared with the old scheme.
