摘要

三维间隙导致刨头-滑架体产生复杂的接触碰撞现象，煤粉层加剧了系统的动态特性。基于刨头与滑架体之间的几何结构特点，提出了将三维多面体碰撞检测降维到二维多边形碰撞检测的方法，综合考虑表面粗糙度、煤粉层的影响，引入粗糙界面接触力模型以及含煤粉层接触力模型，并通过实验测得恢复系数，构建了刨头与滑架体间三维接触碰撞动力学模型，采用数值分析方法获得刨头-滑架体接触碰撞动态特性。研究结果表明：刨头-滑架体的接触碰撞存在点、线、单面、多面等多种形式；随着恢复系数的降低，刨头的摆角振动、位移振动幅值随之降低，在间隙边界处的接触碰撞振动幅值随之减小，各点的碰撞力均值减小，碰撞次数也随之降低。最后通过实验验证了本文碰撞动力学模型的有效性。

Abstract

Three-dimensional clearance causes complex contact collision phenomenon between plow head and sliding framework.Coal powder layer aggravates the dynamic characteristics of the system. Based on the geometric characteristics of plow head and sliding framework, a method of reducing the 3D polyhedral collision detection to 2D polygonal collision detection was proposed. Considering the effects of surface roughness and coal powder layer, a three-dimensional contact collision dynamics model between plow head and sliding framework was established, rough interface contact force model and the contact force model with the coal powder layer were introduced, and the restitution coefficient were measured by experiment. A numerical analysis was conducted to obtain the dynamic characteristics of the contact and collision between plow head and sliding framework. The results show that contact collision of plow head-sliding framework has many forms, such as point, line, single-side and multi-surface.With the decrease of restitution coefficient, angle vibration and displacement vibration amplitude of plow head are reduced, contact collision vibration amplitude at the gap boundary is reduced, and collision force average of each point and the number of collisions decreases. Finally, the validity of the collision dynamics model is verified by experiments.
