Abstract: In view of problems of dispersive design data and difficult knowledge sharing existed in current shearer design, an innovation design service platform of shearer was developed. The platform utilizes key technologies such as dedicated web crawler based on Python, 3D model web page display based on WebGL and parametric CAD/CAE integrated design based on component technology to provide functions of specific innovation design information capture, 3D model web page display of shearer components, remote parametric CAD modeling and remote parametric CAE analysis for designers. The platform provides a lot of innovative knowledge and innovative resource services, which helps to break thinking pattern of shearer designers and can effectively improve innovation design ability of shearer designers and shorten design period of shearer.
