对某吊座在AWE中进行关键尺寸参数化建模,使用ANSYS Workbench的Design Exploration模块进行参数灵敏度分析。以此为基础进行多目标优化,使最大等效应力、最大变形量、重量最小化。最后验算圆整的参数,在保证刚度的前提下,与原设计相比重量下降11.7%,最大等效应力下降4.7%。
對某弔座在AWE中進行關鍵呎吋參數化建模,使用ANSYS Workbench的Design Exploration模塊進行參數靈敏度分析。以此為基礎進行多目標優化,使最大等效應力、最大變形量、重量最小化。最後驗算圓整的參數,在保證剛度的前提下,與原設計相比重量下降11.7%,最大等效應力下降4.7%。
대모조좌재AWE중진행관건척촌삼수화건모,사용ANSYS Workbench적Design Exploration모괴진행삼수령민도분석。이차위기출진행다목표우화,사최대등효응력、최대변형량、중량최소화。최후험산원정적삼수,재보증강도적전제하,여원설계상비중량하강11.7%,최대등효응력하강4.7%。
Firstly ,the parametric model of a hanging seat is set up in AWE ,then the sensitivity of parameters is analyze by using the Design Exploration module of ANSYS Workbench .A multi-objective optimization on the basis of previous job is carried out to minimize the maximum of equivalent stress ,the maximum of total deformation and the mass .At last ,the rounded parameters are checked ,the conclusion is :11 .7% decline in the mass ,4 .7% decline in the maximum of equivalent stress and the rigidity is maintained .
