摘　　要：为了准确预示压力室在发射状态下的结构完整性,对导弹垂直发射系统中的压力室进行结构完整性分析。介绍导弹垂直发射系统,利用数值计算的方法对导弹燃气射流流场进行仿真模拟,将得到的压强分布导入ANSYS结构分析软件得出计算结果,并从应力、应变、形变3个方面对压力室结构进行力学分析。仿真结果表明:压力室在承受8次发射工况后仍具有良好的结构完整性,压力室的应力和形变主要集中在导流板顶端。该仿真结果可为压力室寿命评估工作提供参考。In order to accurately analyze the structural integrity of vertical launching system pressure chamber, missile vertical launching system in the pressure chamber were structural integrity analysis. Introduced the missile vertical launching system, the flow field in the vertical launching system was calculated by the method of numerical calculation, will get the pressure distribution is imported into ANSYS structure analysis software calculation results, and from three aspects of stress, strain and deformation, the structure of pressure chamber is analyzed. The result shows that the pressure chamber has good performance after 8 launches the stress and deformation mainly distributed on the top of deflector. The simulation results can provide reference for life assessment of pressure chamber.
