摘要
根据液化天然气运输过程中的防爆要求,分析了防爆盒隔爆外壳及其零部件的技术要点,提出了应用弹性力学原理对矩形防爆盒进行简化分析和结构设计,并提出了加强筋、法兰和螺栓的强度设计计算方法。介绍了采用ANSYS软件对隔爆壳体的强度进行有限元分析的过程,并根据分析结果对理论结构存在的设计缺陷进行了改进。
According to the requirements of explosion-proof in the process of LNG transportation, It analyzes the technical points of flameproof enclosure and its components,and proposes the application of elastic force of simplified analysis of the tank and flameproof housing design. In addition, it makes a design and calculation method of strength of the stiffener, flange and bolts in tank. Briefly introduces the process of finite element analysis on strength design of flameproof enclosure via ANSYS software, improves the exist defects of theoretical structure according to analysis results.
