短应力线轧机端盖分析与优化设计

Analysis and Optimization Design of End Cover of Short Stress Line Rolling Mill

对短应力线轧机轴承座外侧静迷宫端盖的结构进行优化分析,以减轻端盖的质量、提高端盖的强度与刚度。以减少静迷宫端盖质量和最大应力应变作为优化目标,使用Creo建立端盖的参数化模型,通过ANSYS Workbench进行静力学分析,构建响应曲面模型并进行敏感度分析,最后通过MOGA算法对端盖设计参数进行最优求解。优化后与初始值相比,端盖质量减少了16.58%,等效应力降低了22.10%,等效弹性应变下降了20.39%。优化后实现了端盖的轻量化,提高了设计强度和刚度,为以后短应力线轧机的设计优化提供了参考。

The structure of the static labyrinth end cover outside the bearing seat of the short stress line rolling mill was optimized,so as to reduce the quality of the end cover and improve the strength and rigidity of the end cover.Reducing the quality and maximum stress and strain of the static labyrinth end cover was taken as the optimization objectives,Creo was used to establish the parametric model of the end cover,ANSYS Workbench was used for static analysis,response surface model was constructed and sensitivity analysis was carried out,finally MOGA algorithm was used to solve the optimal design parameters of the end cover.After optimization,compared with the initial value,the end cap mass decreases by 16.58%,the equivalent stress decreases by 22.10%,and the equivalent elastic strain decreases by 20.39%.So the light weight of the end cover is realized,the design strength and rigidity are improved.It provides references for the design optimization of the short stress line rolling mill in the future.
