驻退机试验是舰炮的重要试验项目之一。通过试验测出驻退机活塞承受的液体压力P及活塞后座速度V随时间t和后座行程x的变化规律,求出驻退机产生的后座阻力φ,检验驻退机设计的合理性,为炮架与自动机设计提供依据,也为进一步改进驻退机设计提供依据。测试时,为了得到整个后座行程的压力曲线,测压传感器一般安装在靠近驻退筒底部的位置,如图1。这样测得的是工作腔底部的压力P′。目前在处理测试结果时,一般
Retiming machine test is one of the important pilot project of naval gun. Through testing, we can get the rear seat resistance φ produced by the recoil machine by testing the variation law of the fluid pressure P and the piston rear seat velocity V of the recoil machine piston with time t and rear seat travel x, and test the design of the recoil machine It provides the basis for the design of gun rack and automata, and also provides the basis for further improvement of the design of retrofit machine. During the test, in order to obtain the pressure curve of the entire backseat stroke, the pressure sensor is generally installed near the bottom of the stop cylinder, as shown in FIG. 1. This measures the pressure P ’at the bottom of the working chamber. Currently dealing with test results, in general
