摘要

以煤岩截割理论为依据,模拟了截割过程中滚筒的负载特性;以多柔体动力学为理论依据,建立了截割部的刚柔耦合模型,通过Adams对调高过程进行模拟,得到各铰耳处的负载响应情况;并利用Workbench得到了调高过程中铰耳受力最大时摇臂的应力分布情况;以线性累积损伤法则为理论依据,利用Workbanch对摇臂的疲劳寿命进行估算,验证了可靠性分析及负载响应分析的结果。为研究采煤机截割部的动力学特性及可靠性提供了新的方法。

Abstract

Based on the coal rock cutting theory,simulated the load characteristic of the roller in the process of during coal rock; with the flexible-body dynamics as the theoretical basis to establish rigid-flexible coupling model of cutting unit,simulate the process of height adjustment by ADAMS and get the load response of link point; used Workbench to get the stress distribution of ranging arm when the link point force is maximum during the process of height adjustment; with linear cumulative damage rule as the theoretical basis,used Workbench to estimate the fatigue life of the ranging arm to verify the results of the reliability analysis and load response analysis.This paper provides a new method to research on dynamic characteristic and reliability of shearer cutting unit.
