摘要
掘进机截割电机机壳结构特殊且受力状态复杂,为确保其设计性能满足掘进机截割的各种工况条件,需要对其应力分布规律进行全面了解。对掘进机截割电机机壳建立有限元分析模型,并进行多工况多位置应力分析研究,通过讨论有限元计算结果,从VON MISES等效应力分布出发,全面分析了掘进机截割电机机壳的强度、刚度等结构力学性能。分析结果表明,该截割电机机壳结构设计合理,具有足够的强度和刚度。
The structure of the electric cutting motor chassis for the mine roadheader is special and complicated in a stressed condition.In order to ensure the designed performances meet the each performance condition of the roadheader cutting,it is necessary to have full understanding of the tress distribution law.A finite element analysis model was set up for the electric cutting motor chassis of the mine roadheader.The stresses of the multi performances and multi positions were analyzed and reached.With the discus...
