Simulation research on motion of three machines on fully mechanized coal mining face

摘要: 针对目前综采工作面“三机”运动仿真研究较少涉及单机部件联动过程、不能详细展现单机运动状态的问题,结合虚拟仿真技术建立“三机”几何模型,在对“三机”姿态进行解析的基础上,在Unity3D平台下通过脚本组件,运用面向对象的编程思想,真实还原采煤机摇臂升降及割煤动作,液压支架降柱、移架、推溜等动作,以及刮板输送机弯曲运动。测试结果表明,所建立的模型能够清晰、完全地展现“三机”构造、运行原理及单机运动情况。Abstract: In view of problems that current simulation research on motion of three machines on fully mechanized mining face could not display single-machine motion state in detail, and linkage process of a single unit was rarely involved, geometric model of three machines were established using virtual machine technology. On the basis of attitude analysis, under the Unity3D platform and through script component,object-oriented programming ideas was applied, motions of single machine were restored including rocker arm lifting,coal cutting action of shearer, descending column, moving frame, pushing of conveyer, and bending movement of scraper conveyor. The test results show that the established model can clearly and completely show the structure and operation principle of the three machines and the motion of single machine.
