摘　　要：隔层的正常工作是脉冲发动机功能实现的关键因素,而能否达到绝热要求则是隔层正常工作的重要指标,对隔层的传热过程进行分析是隔层设计的重要环节。本文通过对脉冲发动机一脉冲工作时隔层传热进行数值仿真计算与分析,探讨了隔层厚度、工作时间、隔层导热系数等对隔层传热的影响,为脉冲发动机的方案设计、隔层结构设计和材料选择提供参考。Regular work of insulator is a key factor for operation of pulse motor, while thermal insu- lation meeting requirement or not is an important index for insulator work well, and so the analysis for heat transfer process of insulator is important for insulator design. Through numerical simulation of heat transfer on pulse motor insulator working in first stage, this paper analyses the effects of parameters on heat trans- fer, including insulator thickness, work time and thermal conductivity. The result offers reference for pulse motor project design, choice of insulator material and structural design.
