Abstract

Hydraulic mechanism is widely used in modern machinery and equipment, and its cavitation phenomenon can cause harmful phenomena such as noise, vibration, and hydraulic shock. In this paper, a typical naval gun's recoil mechanism with control rod is selected as the research object, and a two-dimensional model of the flow field in the recoil mechanism is established. The finite element calculation software ANSYS Fluent was used to numerically simulate the internal flow field model before and after considering the cavitation effect, and the physical parameters such as the pressure, flow velocity and composition change of the internal flow field in the recoil mechanism were determined. The simulation results before and after considering the cavitation effect were compared. The recoil resistance test indirectly verifies the correctness of the simulation results. Through experimental observation of the internal parts of the recoil mechanism, the hazard of the internal cavitation effect of the hydraulic components was verified. This research can provide theoretical guidance for the optimization and optimization of hydraulic mechanism performance and vibration and noise reduction.
