摘要
掘进机在截割煤的过程中,受到外界随机动载荷的作用,掘进机的受力情况变得非常复杂,通过建立纵轴式掘进机上下截割时的动力学模型,求解出掘进机在不同工况下的履带振动变化情况,得出掘进机履带在不同工况下的受力仿真曲线,为研究掘进机工作时的动态特性等提供理论依据。
During the cutting operation of the roadheader, the force status of the roadheader is very complicated due to the action of external random dynamic load. After the dynamic model of the longitudinal roadheader simulating upward and downward cutting operation being established, vibration variation of the roadheader＇s track in different operation modes are obtained, and the force simulation curves of the roadheader＇ s track in different operation modes are obtained also. The study offers theoretical basis for studying the dynamic characteristics of the operating roadheader.
