阐述了矿山机械摩擦学设计对于提高经济效益、机械可靠性以及延长机械寿命的重要意义。认为在矿山机械设计中，与结构、强度等设计一样，应设置平行的摩擦学设计；应从润滑、选材及表面处理等方面考虑摩擦学设计问题；建议建立摩擦学设计专家系统以辅助设计. The importance of mining machinery tribology design to improve economic efficiency, mechanical reliability and extend mechanical life is expounded. It is considered that, in design of mining machinery, tribological design should be set up parallel to the design of structure and strength. Tribological design should be considered in terms of lubrication, material selection and surface treatment. It is suggested to establish a tribological design expert system to assist design.
