纵轴式掘进机在横向截割过程中,截割头受到外界随机动载荷的作用,掘进机的侧向受力情况变得非常复杂。通过建立纵轴式掘进机横向截割时的侧向动力学模型,求解出掘进机在不同工况下的履带侧向振动变化情况,得出掘进机履带在不同横向摆角下的侧向受力仿真曲线,为研究掘进机横向截割时的动态特性、稳定性和可靠性提供理论依据,也为其他履带式车辆研究动力学问题提供了参考。
Vertical axis boring machine in the horizontal cutting process, the cutting head by the external random dynamic load effect, boring machine lateral force situation has become very complicated. Through the establishment of the lateral dynamic model of transverse longitudinal cutting of longitudinal boring machine, the variation of lateral vibration of the roadheading machine under different working conditions is solved, and the lateral bearing of the heading machine under different lateral tilting angles is obtained The simulation curves provide a theoretical basis for the study of the dynamic characteristics, stability and reliability of roadheader in transverse cutting, and provide a reference for the research of other tracked vehicles.
