针对现有矿用隔爆箱设计方法的适用范围小、安全裕度过大、浪费材料和缺乏整体性理论分析等问题,采用弹塑性力学方法和SolidWorks Simulation有限元分析法对矿用隔爆箱的耐爆性、隔爆性分别进行静力学计算,并对两种计算结果进行对比。结果表明:SolidWorks Simulation有限元分析法计算结果与弹塑性力学方法计算结果非常接近,符合实际工况,解决了现有设计方法存在的问题,提出了隔爆箱改进方案,缩短了产品设计优化周期。
In view of the problems of small applicable scope, excessive safety margins, material waste and lack of theoretical analysis of the overall design of the existing flameproof box, the elasto-plastic mechanical method and SolidWorks Simulation finite element method Of the explosion-proof, explosion-proof static statics were calculated, and the two calculations were compared. The results show that the finite element analysis results of SolidWorks Simulation are close to those of the elasto-plastic mechanics method, which are in line with the actual working conditions and solve the existing problems in existing design methods. The improved scheme of flameproof box is proposed to shorten the cycle of product design optimization .
