T35型矿用通风机叶片动频仿真分析

Dynamic frequency simulation analysis of T35 mine fan blade

煤矿通风安全一直以来都是矿井安全的重要内容。保障通风安全能够有效预防火灾、瓦斯爆炸等事故的发生,而煤矿通风机性能的安全则在其中起到至关重要的作用[1]。针对通风机在长时间的使用中出现叶片断裂、异常振动等故障,利用Solid Works三维软件,建立通风机的三维实体模型,基于Workbench对T35型矿用通风机叶片的固有振动频率进行了分析,对通风机的结构设计和优化改进提供了积极参考。

Coal mine ventilation safety has always been an important part of mine safety.The protection of ventilation safety can effectively prevent fire,gas explosion and other accidents,and the safety of coal mine ventilator performance plays a crucial role.In view of the fan blade fracture,abnormal vibration and other faults in the long-term use of Solid Works software,the threedimensional solid model of the fan is established,Based on workbench,the natural vibration frequency of T35 mine fan blade is analyzed,which provides a positive reference for the structural design and optimization improvement of the fan.
