Boomer 281台车拐臂静力学结构强度有限元分析

Finite Element Analysis on the Static Structural Strength of the Connecting Lever of Boomer 281 Trolley

推进补偿拐臂作为Boomer系列掘进台车中的关键零部件之一,其结构强度和使用寿命对整机的使用寿命和安全性有直接影响。根据拐臂位置和结构,进行静力学分析,找出拐臂与拐轴垂直相交处的危险截面。在建立的拐臂三维模型的基础上,探讨了拐臂的边界条件,采用有限元强度分析方法,计算了拐臂拐轴的应力应变,对于提高设备的维护管理水平具有一定的作用。

The propel compensation connecting level as the key components of the Boomer series driving trolley, the structral strength and fatigue life of the Boomer 281 trolley are infulenced directly by the ones of the propel compensation connecting lever. According to the location and structure of connect- ing lever, the statics analysis is conducted so as to looking for the danagerous section that located in area of the connecting lever and turn the shaft vertical intersection. The boundary conditions of the connecting lever is discussed based on establishing the 3D model of the connecting lever, besides that, the finite ele- ment analysis is adopted to calcuate the stress and strain values of the turn the shaft of connecting lever. The research results in this paper can provide some reference for improving the equipment maintenance maangement level.
