摘　　要：对煤气罐进行了设计计算,建立了三维模型,运用有限元分析软件对煤气罐施加工作压力,得到了工作状态下煤气罐的应力值。根据应力分析结果对煤气罐的壁厚进行了优化分析,得到了设计序列、体积与迭代次数的关系曲线、厚度与迭代次数的关系曲线、最大应力与迭代次数的关系曲线,为其他压力容器的应力分析和优化设计提供了思路。In the paper, the gas tank is designed and calculated, the three-dimensional model is established, and the stress value in the working state is obtained by of the finite element analysis software. The optimized design of wall thickness is completed according to the results of stress analysis, the design procedure, relationship curve of the number of iterations, volume, thickness and maximum stress are gotten. The result of design can provide a method for stress analysis and optimization design for the other pressure container.
