Condition Monitoring Method and Evaluation of Gun Recuperator

The technical state of counter recoil mechanism is the key index affecting the health state of artillery. It mainly monitors the technical status of the recoil mechanism by detecting the air pressure and liquid volume of the recoil mechanism.The Gun Recuperator is a multi-layer nested high-pressure closed container, which is filled with recoil liquid and compressed nitrogen. The air pressure is detected by a pressure sensor. On the premise of changing the internal volume of the counter recoil mechanism, the pressure signal is measured, and then converted by the intelligent instrument. There are some methods to measure the liquid volume of the recuperator, and the performance of each method varies greatly. By summarizing and analyzing the current liquid volume measurement methods on recuperator，and the fuzzy calculation method is used to evaluate its comprehensive performance, The results show that the air-source closed detection method has the best comprehensive performance, followed by the electric pump source open injection and discharge method. This result provides a preferred basis for decision makers to select the appropriate detection method.
