摘　　要：针对煤矿井下隔爆主机重量大、加工成本高、搬运移动便捷性差等问题,对现有的隔爆主机壳体进行理论计算和结构优化设计,实现在保证结构强度的情况下降低壳体质量的目的,并利用有限元方法对隔爆壳体进行仿真分析。结果表明,壳体采用7 mm厚的高强度钢板焊接,在壳体内部薄弱处设置加强肋,外部散热部位增加散热肋板同时起到增加强度和散热的作用,在满足性能的前提下壳体质量降低了54%,大幅减少了加工成本。In response to the problems of heavy weight,high processing cost,and poor transportation and mobility of explosion-proof host computer in coal mine,the theoretical calculation and structural optimization design were carried out on the existing shell of explosion-proof host computer,the aim of reducing the shell mass while ensuring the structural strength was realized,and finite element method was used to simulate and analyze the explosion-proof shell.The results shows that the shell is welded with high-strength steel plates with a thickness of 7 mm,and reinforcement ribs are set at the weak points inside the shell,and the heat dissipation ribs at the external heat dissipation part of the shell has simultaneously strengthening the strength and heat dissipation function.Under the premise of meeting performance requirements,the weight of the shell is reduced by about 54%,processing costs is greatly reduced.
