摘要
反后坐装置是火炮射击故障率最高的部件之一。驻退机故障主要体现在驻退机内液量不足及节制环、驻退杆活塞套等零件磨损,完整火炮难以直接测量内部零件磨损量,因而驻退机故障诊断困难。通过建立反后坐装置后坐、复进运动数学模型,对射击中出现的驻退机故障及其原因进行了仿真计算,应用改进的遗传算法诊断了其故障原因,并用诊断实例验证了该方法的正确性与有效性。实例证明,该方法在火炮反后坐装置故障诊断方面具有速度快、精度高等优点,为火炮结构优化设计及故障论断提供参考。
The recoil system is one of the parts of the highest faults during gun firing. The main faults of recoil brake are lack of liquid, wear of throttling ring, piston cover of recoil rod and other parts. Complete gun system is difficult to carry out direct measurement of wear of internal parts, so fault diagnosis of re- coil brake is very difficult. Based on analysis of mathematic model of gun recoil and count-recoil movement of recoil mechanism, the faults of recoil brake and its causes were simulated and calculated by computer, and the faults of gun fire were diagnosed by means of improved generic algorithm. The correctness and ef- fectiveness of algorithm were validated by an example of diagnosis..The calculation results showed that this method has faster speed, higher precision in the fault diagnosis of gun recoil mechanism. It can provide references for structure optimum design and fault diagnosis of the gun system.
