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

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.
