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-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固体火箭发动机舰载寿命的评估方法。
In order to estimate the life of a long-term guided missile solid rocket engine, the load caused by the ship’s swaying motion on the engine charge under various sea conditions was analyzed. Based on the stress-strain calculation of the engine charge, Can estimate the cumulative life-span of ship-borne missile solid-propellant rocket engine in different sea areas.
