| 摘 要： | 为了预估海洋环境温度对舰载导弹固体火箭发动机的累积损伤作用,保证发动机的正常工作,以2个海区为环境对象,通过环境温度模型、传热模型和粘弹性本构关系,用有限元法求解了舰载导弹固体火箭发动机对海洋环境的温度和应力响应,得到了发动机中的温度分布和应力分布.结果表明,同样粘结强度时,发动机第一粘结界面比第二粘结界面更容易脱粘;药柱中星尖处应力最大,是产生裂纹的危险部位;冬季是发动机药柱容易产生裂纹的危险季节.

| Abstract: | In order to predict cumulative damage effects of sea environmental temperature on the solid rocket motor of the ship-based missile and ensure normal operation of the motor.The temperature respond and stress respond of the motor to two environmental temperatures were found by finite element method on the basis of the environmental temperature model,heat transfer model and viscoelastic constitutive relation.The temperature profiles and stress profiles of the motor were obtained.The results indicate that the f... |
