武器发射装置长期贮存中的蠕变研究

Weapon Launcher Creep During Long-Term Storage

武器发射装置在长期贮存过程中,随时间推移会出现蠕变现象。为研究其对武器发射的影响,基于有限元方法对武器长期贮存及其发射过程进行了仿真,研究了发射倾角与贮存时间对发射装置中的蠕变及贮存后武器发射过程的影响。研究结果表明:发射装置在贮存过程中经过约1年时间结束瞬态蠕变阶段,进入稳态蠕变阶段,武器受底部承载装置蠕变的影响发生偏转,且偏转量与发射倾角和贮存时间成正相关;经过长期贮存后进行发射的武器偏离了初始发射轴线,贮存过程中蠕变对发射装置结构和武器发射过程产生的影响不可忽略。

During the long-term storage of weapon launchers,creep will occur over time.The longterm storage of weapons and their launch process are simulated based on the finite element method to study the influence of creep on weapon launch.Meanwhile,the effects of launch angle and storage time on the creep in the launcher and the weapon launch process after storage are analyzed.The results show that the launcher ends the transient creep stage after about one year during storage and enters the steady-state creep stage.The weapon is deflected by the creep of the bottom carrying device,and the deflection is positively correlated with the launch angle and storage time.The weapon launched after long-term storage deviates from the initial launch axis,and the influence of creep on the launcher structure and the launch process of the weapon during storage cannot be ignored.
