摘　　要：摩擦式膜片弹簧离合器的并行优化设计,区别于以往单独优化摩擦片或膜片弹簧来提高离合器的工作性能。通过分析摩擦片和膜片弹簧相同的内、外工作环境因素,明确摩擦片和膜片弹簧两部件优化相互影响因素的耦合关系以及它们之间的工作配合关系来进行并行优化设计以提高离合器的工作性能。权衡各优化目标的权系数,运用改进的遗传算法快速求得更加精确并避免陷入局部解的全局最优解,使得经过并行优化设计后的摩擦片和膜片弹簧处于最佳配合工作状态。The parallel optimization design of the friction type diaphragm spring clutch is different from former separately opti mizing friction plate or the diaphragm spring to improve the overall performance. It is based on analyzing the same inside and outside work environment factors of friction plate and diaphragm spring and being clear of the coupling relationship between them to improve the integrated overall performance. Balance each optimal target＇s weight coefficient,choose the improved GA strategy to get a more accurate global optimal solution rapidly and avoid getting into a local solution. It can get a best work coop- eration state after the parallel optimal design of friction plate and diaphragm spring.
