某型枪榴弹公路运输振动试验与损伤分析

Vibration Test and Damage Analysis of Certain Rifle Grenade under Highway Transportation

针对公路运输振动条件下的弹药安全问题,以某典型枪榴弹为对象,根据损伤等效原理,通过设计运输振动模拟试验和跑车试验,对不同设计车速下振动环境对枪榴弹安全性的影响进行了研究。结果表明:试验激励的振动环境对该型枪榴弹的质量和性能影响不大,各项分析指标在试验前后无明显变化,现行包装设计满足防护要求;从运输振动环境角度来看,以试验设计速度进行枪榴弹运输是安全的,我军现行运输规定偏于保守,不利于保障效率的提高。

Taking certain rifle grenade as research object, the simulation test based on equivalent damage principle and field test were carried out, by considering ammunition security under highway transportation vibration, These results indicated that the excited vibration has no clear influence on the rifle grenade performance, and the indexes can remain consistent before and after tests, the package also meet the requirements of protection. From the aspect of transportation vibration, the transportation standard of our army is conservation, which is adverse to the improvement of support efficiency, and it is safe to transport by design velocity.
