摘要
通过对锤片式粉碎机转子的工作特性进行分析,构建了转子主轴应力及应变优化数学模型。运用Solidworks软件构建锤片式粉碎机转子的结构模型,同时以主轴最大应力与最大应变为目标函数,提出了3种多目标优化方案,在满足主轴机构尺寸约束的情况下,提出利用ANSYS Workbench软件对主轴进行优化的思路。优化后,分别将3种方案的优化结果与原方案进行对比分析,选出最优方案,使转子主轴最大应力与最大应变较初始值设计都得到了一定程度的降低,达到了改善粉碎机结构性能的目的。
By analyzing the working characteristics of the hammer mill rotor,an optimized mathematical model of the rotor spindle stress and strain is constructed.Solidworks software is used to construct the structural model of the hammer mill rotor,the maximum stress and maximum strain of the spindle is taken as the objective function and three multi-objective optimization schemes are proposed.Under the condition of the spindle mechanism size constraint,the idea that the ANSYS Workbench software is used to optimize the spindle is proposed.After optimization,the optimization results of the three schemes are compared with one of the original scheme respectively.The best one is chosen from 3 schemes,it can be used to reduce the primary design value of the maximum stress and maximum strain of the rotor spindle,thus improving the performance of the pulverizer structure.
