摘　　要：该文通过理论建模、Workbench有限元软件仿真和光纤布喇格光栅测量对存储惰性气体的某型号高压球形压力容器承压结构的应力分布进行了理论和实验分析研究,得出承压结构在工作条件下的应力分布规律,为其安全性能评估提供了理论和实验参考。在仿真实验的基础上将性能优越的光纤布喇格光栅引入该型号压力容器承压结构应力检测中,通过实验测量结果与仿真结果对比分析得出光纤布喇格光栅在应力检测方面的良好性能,为该类型球形压力容器的结构应力测量探寻出新的检测手段。In this paper, the stress distribution of high pressure spherical pressure vessel for storing the inert gas is studied through the theoretical modeling, finite element simulation with Workbench and fiber Bragg grating measurement. The stress distribution law of the pressure structure under the condition of the work has been obtained, which provides the theoretical and experimental reference for the safety performance assessment. Based on the simulation experiment, the optical fiber Bragg grating is introduced into the stress testing of the pressure vessels under pressure structure. It has been shown that the fiber Bragg grating has good performance for the stress testing through comparing the experimental results with the simulation results. This proposed work has explored a new detection means for this type of spherical pressure vessel structure stress measurement.
