| 摘 要： | 针对导弹长期储存升力面扭片刚度衰减问题,用损伤力学的方法给出了扭转力矩随时间变化的解析解,并对解析解进行了数值模拟。结果表明,刚度衰减主要发生在开始阶段,因此研制阶段扭片储存试验不需要太长的时间。

| Abstract: | To solve the problem of stiffness attenuation of torsion slip in view of missile long time storage,the theoretical model which the variety of torsion moment vs time are obtained by using damage mechanics method,at the same time the theoretical model were simulated by numerical method.It is indicated that the stiffness attenuation mainly occures in the beginning stage and the experimentation of torsion slip storage in research and development stage need not cost a long time. |
