摘要
目前工程机械行业发展快速,挖掘机在施工中扮演着重要角色,但挖掘机在工作中能量利用率低,造价昂贵,因此对挖掘机部件进行模态分析和轻量化设计具有重要意义。该文主要是对挖掘机的液压缸进行模态分析和轻量化设计,使用UG软件建立液压缸三维模型,然后导入ANSYS中进行模态分析和轻量化设计。在满足正常工作的条件下,以液压缸缸筒总质量最小为优化目标。通过结果分析,经过优化过后的液压缸缸筒,最大应力减少了4.8%,最大变形量减少了5.2%,质量减少了4.7%。
At present,the construction machinery industry is developing rapidly,and excavators play an important role in construction,but excavators have low energy utilization during work and are expensive.Therefore,modal analysis and lightweight design of excavator components are of great significance.This article mainly carries on the modal analysis and lightweight design to the hydraulic cylinder of the excavator,uses UG software to establish the three-dimensional model of the hydraulic cylinder,and then imports it into ANSYS for modal analysis and lightweight design.Under the normal working conditions,the total mass of the hydraulic cylinder is the optimization goal.Through the analysis of the results,the optimized hydraulic cylinder barrel has reduced the maximum stress by 4.8%,the maximum deformation by 5.2%,and the mass by 4.7%.
