摘　　要：为研究连续航行状态下舰船振动对固体发动机的影响,针对某型固体火箭发动机,分析了其在不同舰船振动载荷作用下的界面剪切应力变化特性,分析了不同海况下舰船振动对固体火箭发动机界面剪切应力的影响。研究结果表明,固体发动机界面剪切应力变化周期受海况变化影响较小,基本维持在0.2s左右不变;不同海况作用下界面剪切应力绝对值大约在5KPa-10KPa范围内变化,远低于界面剪切应力强度值;随着海况增加,界面剪切应力变化幅值越来越大,其交变特性带来的影响不可忽略。研究可为该型固体火箭发动机寿命评估和延寿工作提供技术支持。To study the influence of ship vibration on solid rocket motor in continuous navigation,to analyze the characteris-tics of interface shear stress change under different ship vibration loads for a solid rocket motor,to analyze the influence of The vi-bration on solid rocket motor interface shear stress. The results show that the shear stress variation cycle of the solid rocket motor isless affected by the change of the sea condition,and it is basically maintained at about 0.2 s. The absolute value of interfacial shearstress in different sea conditions is about 5 KPa-10 KPa,which is much lower than the interfacial shear stress intensity. In the atro-cious sea condition,the amplitude of interfacial shear stress is increasing,and the impact of its alternating characteristics cannot beignored. The study can provide technical support for the life evaluation and life extension of the solid rocket motor.
