摘要:
以某型号装载机动臂为研究对象,利用三维建模软件Solidworks建立三维模型,通过中性文件parasolid将模型导入Workbench中,建立有限元分析模型。通过油液体积弹性模量经验公式计算油液弹性,基于Workbench软件完成约束设置,进行不同断面形状动臂的模态分析以及动臂截面不同长厚比的模态分析,计算装载机发动机怠速时的激振频率,为装载机动臂结构的减振设计和动态特性优化提供理论参考。
Abstract:
Taking the boom of a certain type of loader as the object, the research established the finite element analysis model by importing the 3D model which was set up by Solidworks into Workbench by the neutral file Parasolid. The oil elastic was firstly calculated by the empirical formula of oil volume modulus; and then, the constraints settings was done with Workbench; thirdly, the modal analysis were conducted on the boom with different section shape and on the different aspect ratio of the boom section respectively; finally, the vibration frequency of the loader was calculated when the engine idling. The research could provide theoretical references for the vibration reduction design and dynamic characteristics optimization of the boom structure of the loader.
