Finite element analysis of vibration absorber for electric cabinet of roadheader

在对橡胶减振器设计和计算的基础上,应用Ansys有限元分析软件对其受到径向载荷压缩时橡胶层和内外钢圈的静强度进行非线性分析,分析结果表明,减振器在受到径向载荷作用后应力和应变都表现出明显的非线性特征,其中橡胶层的最大应力和应变均发生在橡胶层内圈靠近底部位置,而应变主要集中在橡胶层内圈与内钢圈接触部分;内外钢圈最大应力发生在内钢圈左右两侧中间部位处,计算结果表明减振器的设计能够满足使用条件,研究结果为采煤机电控箱减振器的设计和应用提供指导。

In this paper,based on the design and calculation of the rubber vibration absorber,the static strength of the rubber layer and the inner and outer steel rings when subjected to radial load compression is analyzed nonlinearly using Ansys finite element analysis software.The analysis results are as follows:the stress and strain of the vibration absorber show obvious nonlinear characteristics when subjected to radial load;the maximum stress and strain of the rubber layer occur near the bottom of the inner ring of the rubber layer,and the strain is mainly concentrated at the contact part of the inner ring and the inner steel ring;the maximum stress of the inner and outer steel rings occurs at the middle of the left and right sides of the inner steel ring.The calculation results show that the design of the vibration absorber can satisfy the working conditions.The research results has provided guidance for the design and application of the vibration absorber for electric cabinet of roadheader.
