摘要
为了更好实现赛车的轻量化设计目标,针对制动踏板,利用拓扑优化的方法对制动踏板进行结构优化并重建模型,并与原始制动踏板做强度分析与疲劳分析的结果对比。结果表明,拓扑优化设计后的制动踏板,其变形量、应力分布均好于原始制动踏板,并且质量降低了22.1%,实现了轻量化设计目标,对赛车零部件设计思路具有一定的指导作用。
In order to achieve the lightweight design goal of racing car better,For the brake pedal,the topological optimization method is used to optimize the structure of the brake pedal,then rebuild the model.At the meanwhile,the results of strength analysis and fatigue analysis are compared with the original brake pedal.The result shows that the deformation and stress distribution of the brake after topology optimization design are better than that of the original brake pedal,and the quality is reduced by 22.1%,achieving the goal of lightweight design.The paper has a certain guiding effect on the design of racing car parts.
