| 摘 要： | 为了解决固体导弹发动机提前退役带来浪费和过期服役可能导致发射失败的问题,利用定期解剖常温自然贮存的发动机来测试推进剂的力学性参数,结合三维粘弹性有限元分析方法,对贮存一定时期的导弹发动机在常温和低温下点火发射进行数值仿真,由最大Von Mises应变及推进剂应变强度随贮存时间的变化规律来评估发动机的安全性,确定不同地区贮存的导弹发动机的贮存寿命.

| Abstract: | The wasteful problem which was caused by early out of commission of solid rocket motor(SRM) and the safety problem caused by delayed ex-service of SRM must be solved after the SRM was equipped.The mechanical property parameters of the SRM grain after stored naturally for a certain period of time were obtained by dissection of the SRM.When the SRM was launched under normal and low temperature condition,the maximum Von Mises strain of the SRM grain was calculated with three-dimension finite element method res... |
