摘要
为了优化节能赛车车架的结构,对车架进行动、静刚度分析。以车架质量最小为优化目标,应用Opti Struct软件进行拓扑优化设计,得到车架结构的最佳材料分布方案。从应力、变形、模态特性等方面,全面比较优化前后的节能赛车车架的静强度、静刚度和动刚度。通过实车试验,验证了优化设计的有效性和准确性。结果显示,优化后的车架质量减轻37%,保证了强度和刚度要求,并满足了模态特性需求。
In order to optimize the structure of energy-saving car frame, the dynamic and static analysis of the car frame were carried on. For the goal of the frame＇s weight minimum, OptiStruct software was used to topology optimization design. And the optimal material distribution program of the frame structure was got. Static strength, static stiffness and dynamic stiffness be- fore and after optimization were comprehensive compared through the stress, deformation, modal characteristics and other as- pects. Through real car experiment, the effectiveness and accuracy of the optimization design were verified. The results showed that the weight of frame after optimization was reduced by 37% , and the requirements of the strength and stiffness were ensured. The requirement of modal characteristics was met.
