摘要
锁紧钩是垃圾压块机自推机构与压缩机构的连接组件,起到重要的锁紧作用.提高锁紧钩的综合强度,对保证整体设备安全运行有着重要意义.论文在Workbench平台对锁紧钩进行静力学分析,得到应力、应变和变形云图.对设计参数进行灵敏度分析,筛选出对目标结果影响程度较大的参数,通过响应面法构建出设计参数与目标结果之间的近似函数关系.建立锁紧钩优化数学模型,使用多目标遗传算法进行优化,得到优化设计的Pareto解集,确定出最佳设计点.结果表明最大应力值下降11.65%,最大变形量下降16.90%,锁紧钩的综合强度得到较大提高.
Abstract
The locking hook is the connecting component of the self-pushing mechanism and the compression mechanism of the garbage press,which plays an important role in locking.It is of great significance to improve the comprehensive strength of the locking hook to ensure the safe operation of the whole equipment.This paper performes the static analysis of the locking hook on the Workbench platform to obtain the stress,strain and deformation cloud diagram.It carries out the sensitivity analysis of the design pa-rameters,and screenes out the parameters which have a greater influence on the target results,constructes the approximate function-al relationship between the design parameters and the target results by response surface method.It establishes the mathematical mod-el of the locking hook optimization,obtaines the Pareto solution set of the optimization design by using the multi-objective genetic algorithm,and determines the optimal design point.The results show that the maximum stress value decreases by 11.2%,the maxi-mum deformation decreases by 16.9%,and the comprehensive strength of the locking hook is greatly improved.
