摘　　要：应用基于正交试验优化设计的方法对梭式皮带布料机下回转支座的强度进行分析研究,对初始设计下的布料机下支承座结构进行了有限元分析,针对它刚度满足要求,但强度不满足要求的情况,以下支承座结构的筋板厚度、筋板个数、过渡圆角半径以及上盖板厚度为影响因子,采用正交组合试验优化设计分析的方法,对四种因素组合影响下的结构进行基于有限元法的试验分析评价,得出了各因素水平的指标评价体系,并提出了最佳组合改进方案。优化结果表明,下支承座的强度性能明显提高,优化结果为同类结构的优化设计提供了理论依据。A orthogonal test optimum design methodology was applied in the intensity analysis of shuttle belt conveyer slewing bearing, the finite element analysis was used to analyze the structure of the belt conveyer＇s lower supported structure in the condition of initial design. Aeeording to the condition that its stiffness meet for the requirements, but the strength can ＇ t meet, four factors which is the muscle thickness, the rib number, the rib fillet radius and the thickness of upper cover plate was selected. Then experimental analysis of the structure within different factors was carried out using orthogonal test optimization design. By the analysis the index evaluation of each factor was gotten in this paper. At last the optimum factor eombination was provided to make the stiffness. The optimization results show that the performanee of the lower bearing＇ intensity can be improved significantly, the study ean also provide a theoretical basis to optimize the same structure design.
