| 摘 要： | 为了预估长期远航舰艇的导弹固体火箭发动机舰载寿命,分析了各种海况下舰船摇摆运动对发动机装药形成的载荷;在对发动机装药应力一应变计算的基础上,利用基于耗散能的装药累积损伤理论,提出了在不同海域执行任务的舰载导弹尚体火箭发动机舰载寿命的评估方法.

| Abstract: | In order to predict the shipborne lifespan of the solid rocket motor of missile on ships which navigate on remote ocean for long time,the loads on the motor grain from ship swing motion in various sea situations were studied.Based on calculations of the stress-strain field for motor grain,the method of shipborne lifespan for solid rocket motor in various sea zones was presented by damage cumulative theory of grain on dissipative energy. |

| Keywords: | Shipborne missile Solid rocket motor Dissipative energy Ship swing Stress-strain |
