Abstract

A periodic oscillation in the working chamber pressure was observed in the pressure test data of the recoil mechanism, with an amplitude accounting for 6% of the maximum pressure. This pressure fluctuation affects the calculation of the hydraulic resistance of the recoil mechanism. In previous studies, pressure oscillations were generally considered to be noise introduced by sensors, and earlier calculation methods failed to capture the pressure oscillations in the working chamber. Since the outer tube of the recoil mechanism is a thin-walled, long-cylinder component, this study takes its radial expansion stiffness into account and establishes an equivalent spring-mass model, using a non-oscillatory pressure curve as the model input. The comparison between the calculation results and experimental data shows that the calculated curves under different operating conditions closely match the experimental curves. Moreover, the oscillation frequency of the calculated results is very close to that of the experimental results, indirectly proving that the pressure oscillations in the working chamber of the recoil mechanism are caused by the radial expansion of the outer tube.
