Abstract
The poor working condition and complex workload of coal mining machine lead to a big risk and a high cost for the test based on physical prototype, while the application of virtual prototype for simulation can acquire a comprehensive assessment of the reliability of product at the design stage. Parameters of working condition were obtained through the coal mine physical and mechanical property testing, and according to the coal-breaking mechanism and numerical analysis theory, the workload calculation and application methods of static and dynamic coal mining machines were analyzed with the examples of plow and shearer. In addition, the load calculation program was written in MATLAB. Based on interface technology, the rigid-flex coupled virtual prototype was established by the adoption of ADAMS, Pro/E and ANSYS, and then the problems in design were found through interference examination and dynamic analysis. The process above provided the basis for optimizing design.
