药筒射击时出现卡壳原因分析及测试方法

为判断火炮射击时出现卡壳现象的原因是药筒问题还是火炮问题，对卡壳原因进行分析，并对其测试方法进行研究。具体的测试方法为：先根据应变片测得电流大小，计算出抽壳力。当遇到卡壳时，再测出卡壳力的大小，将卡壳力的大小与火炮实际抽壳力的大小相比较，如卡壳力小于火炮抽壳力，则说明出现卡壳现象是火炮抽壳故障所致；反之，说明卡壳原因是因为药筒卡壳力过大所致。结果显示，该方法简单易行、操作可靠、数据准确，有重要的理论和使用价值。

Cause Analysis and Testing Method of Stoppage When Cartridge Shooting

To determine when artillery stuck because of the phenomenon of cartridge problem or artillery problem, analysis the cause of stoppage and research the testing method, there are: calculates the extraction force basis the electric current of strain gauge. When stoppage happens, compares it with artillery actual extraction force, tests the stoppage force, if former is less than later, shows cause of stoppage from artillery, whereas, reveals cause from excessive stoppage force of cartridge case. Result shows th...
