Based on genetic algorithm optimal design on diaphragm spring by MATLAB

离合器膜片弹簧是根据汽车离合器的分离需要和结构布置进行设计。运用载荷特性曲线分析了多种约束条件的形变,在参考现存成熟的结构参数基础上提出了一种优化设计数学模型。利用MATLAB对该数学模型优化,稳定储备系数提高了离合器可靠性。通过遗传优化算法实例设计分析结果表明优化设计后的各项参数较优于原设计值。

Clutch diaphragm spring is according to the needs of automobile clutch separation and the design of structural layout design, this paper sets up the load characteristic curve of constraint analyzed the variety conditions of deformation. Base on the existing mature structural parameters puts forward the optimum design mathematical model. Using MATLAB to the optimization mathematical model, stability factor improves the reliability of the clutch. Through the design instance of genetic optimization algorithm and analysis results indicate that the optimization design of parameters is better than the original design＇s value.
