Research on Temperature Adaptability of Special Buffer Oil Cylinders

During the research on vibration and noise reduction of underwater weapons, it was found that the special buffer oil cylinder, as an important transmission component, is one of the main sources of noise. Therefore, the design of the buffer device for the special buffer oil cylinder is important, and the prediction of the buffer effect is the core of the buffer design. Due to the special working conditions, special buffer oil cylinders are mostly in standby mode. When a startup is started after a long interval, the hydraulic oil temperature in the buffer chamber is equal to the installation environment temperature. There will be a large temperature difference in the hydraulic oil in the buffer chamber between the first startup and subsequent startups. In order to ensure that the working requirements can be met even under extreme temperature conditions, temperature adaptability research needs to be conducted on the special buffer oil cylinders. Firstly, a mathematical model of the motion process of a special oi
