轮式装载机两种动臂结构的力学性能对比分析

对装载机两种类型的工作装置——六连杆工作装置与八连杆工作装置进行简要介绍,并对其主要部件动臂进行结构力学对比分析.首先,分析在装载机典型作业过程中动臂的承载工况与作业载荷,其中重点分析偏载工况下动臂承载的特点.其次,建立两种动臂的有限元分析模型,为了提高分析的准确性,采用接触单元法来模拟动臂与销轴之间的连接作用.最后,...

Comparison Analysis of Mechanical Performances between Two Kinds of Boom for Wheel Loaders

In view of two kinds of loader attachment,i.e.6-linkagte and 8-linkage attachment systems with brief introduction we have gone thru comparison and analysis with structural mechanics on major components in the lift arm.Firstly,the analysis was done on loading conditions and operation load during the loader's typical operation processes,including emphasized analysis of characteristics in the lift arm under partial load conditions.Secondly,we set up models for finite element analysis on 2 types of lift arm so ...
