汽车离合器圆柱螺旋压紧弹簧的优化设计

Optimum Design of Cylinder Helix Spring for Automotive Clutch

用传统方法设计汽车离合器螺旋压紧弹簧过程繁琐,且难得到参数的最优值.以螺旋压紧弹簧的中径、旋绕比、弹簧数量为设计变量,螺旋压紧弹簧质量最小为设计目标,建立了汽车离合器螺旋压紧弹簧的优化设计数学模型,并用内点惩罚函数法对一实例进行了优化设计,优化后的离合器螺旋压紧弹簧不但满足使用性能而且弹簧质量减轻、数目减少,验证了方法的有效性.

Design procedure of cylinder helix spring for automotive clutch is tedious by using traditional method,and it is difficult to find the optimum parameter.The mathematical model of optimization design was established through choasing design goals of mean diameter,wind around ratio spring number.An example was designed by using internal penalty function method.The result shows that the method is effective.
