The 3D Modeling and Characteristic Analysis of EBH300 Roadheader

The EBH300 Roadheader is one of the important equipment in laneway excavation of coal mine. It composed of mechanical, hydraulic, electrical and control systems, and covered cutting, shipment and travelling. Because of its hard working conditions, the complex cutting force and load fluctuation and vibration during the working process, the mechanical parts design plays very important roll to the EBH300 Roadheader. The 3D models of the EBH300 Roadheader were built based on the engineering prototype. The mechanical characteristics were studied for further development, which included mechanical structure, the vibration modes of the cutting parts, maximum amplitudes by modal analysis. According to the result, more attention must be paid to the complex force condition, violent and irregular vibration of the cutting parts in the design.
