摘要
为了得到轻量化的赛车制动踏板,将拓扑优化方法引入到踏板的结构设计中,建立了轻量化优化设计的数学模型;并对踏板初始设计几何模型进行了3种受力情况的减重优化,得到质量分别减少301.5,319,293.95 g的3种拓扑结构;最后,根据实际工况和机加工工艺要求选择第2种方案进行了强度、安全系数和寿命的仿真校核和样件的加工制造,并装配到赛车上进行了物理实验。结果表明,优化设计的制动踏板满足工作要求。
In order to obtain a lightweight racing brake pedal,the topology optimization method was introduced into the structural design of the pedal,a mathematical model of lightweight optimization design was established,and weight reduction optimization of the pedal initial design geometric model was carried out.The three topologies with mass reduction of 301.5 g,319 g and 293.95 g were obtained respectively.Finally,the second scheme was selected according to the actual working conditions and the machining process requirements,and the simulation check of the strength,safety factor and service life was carried out and the sample was manufactured and assembled into the car for physical experiments.The results show that the optimized design of the brake pedal meets the work requirements.
