摘要
以某乘用车通风前制动盘为研究对象,将制动盘各主要结构参数作为制动盘优化设计的设计变量,以制动盘的单次制动温升、连续10次制动温升、热变形、模态和应力作为制动盘优化设计的约束条件,同时将制动盘的质量最小作为制动盘优化设计的目标,基于创建的响应面分析模型进行制动盘的多学科联合优化设计,为汽车制动盘的多学科联合优化设计提供理论依据和参考.结果表明,多学科联合优化后的制动盘仿真分析结果均同时满足要求,同时制动盘基于响应面分析模型进行多学科联合优化结果的误差值均在可接受范围内,表明制动盘多学科联合优化结果是可靠的.
Abstract
The research object was a ventilated front brake disc of a certain passenger car.The main structural parameters of the brake disc was used as design variables for optimizing the design of the brake disc.The optimization design of the brake disc was constrained by a single brake temperature rise,10 consecutive brake temperature rises,thermal deformation,mode,and stress.Meanwhile,minimizing the mass of the brake disc was the goal of optimizing the design of the brake disc.Multidisciplinary joint optimization design of brake discs was conducted based on the created response surface analysis model,to provide theoretical basis and reference for multidisciplinary joint optimization design of automotive brake discs.The results showed that the simulation analysis results of the brake disc after multidisciplinary joint optimization met the requirements.The error values of the multidisciplinary joint optimization results of the brake disc based on the response surface analysis model were within an acceptable range,which indicated that the multidisciplinary joint optimization results of brake discs were reliable.
