摘　　要：为深入研究变壁厚涡旋膨胀机的型线参数,文章以高次曲线组合型线和圆弧组合型线为例,建立了一种新的优化模型-涡旋型线占积比;讨论分析了型线参数对型线面积和占积比的影响;运用单目标遗传算法对占积比取得极值时的2种组合型线参数取值进行了优化,并运用多目标遗传算法讨论了型线面积和占积比同时优化时的非劣解集及对应参数的选取。该文的研究为变壁厚涡旋膨胀机型线参数的选取提供了一定的参考。In order to further study the profile parameters of variable wall thickness scroll expander,a new optimization model of the scroll profile area ratio is established by taking the combined profile of high-order curve and circular arc as examples.The influence of profile parameters on the profile area and area ratio is analyzed.The single objective genetic algorithm is used to optimize the parameters of two combined profiles when the area ratio reaches the extreme value.The multi-objective genetic algorithm(MGA)is used to discuss the non-inferior solution set and the selection of the corresponding parameters when the area and the proportion of the profile are optimized simultaneously.It provides a reference for the selection of the profile parameters of the scroll expander with variable wall thickness.
