基于Inventor FEA模块的移载机械手提升手臂静力学分析

摘要

通过在Inventor环境中建立了移载机械手提升手臂的三维模型,运用Inventor的FEA模块对提升手臂进行了静力学仿真,分析计算出了提升手臂的应力、变形等力学性能参数,最终验证了该手臂的设计合理性.同时,提出了一种在Inventor中建模并直接在其中进行有限元仿真分析的方法,该方法一定程度上解决了三维软件与其他仿真分析软件之间的转换操作的繁琐和数据在转换中出现丢失的问题,在实际工程运用中实用、效率高,对相关工程技术人员具有一定参考意义.%In this paper,the 3D model of lifting arm device of conveying manipulator is established based on Inventor 3D software and the finite element statics analysis are then carried out on this 3D model by using the FEA module provided by the inventor itself.The analysis calculates the mechanical performance parameters of the model,such as the stress and strain distribution,and so on.As a result,the validity of the proposed model and method are verified by the finite element statics analysis.Moreover,the proposed analysis method in the paper,to a certain extent,solves the problems of the inconvenient operation of converting data between the Inventor and other analysis software and the loss of information during the converting.Meanwhile,this method is practical and highly efficient,and has certain reference significant for related engineering technicians.
