Simulation Study on Dynamic Analysis of Spring Type Needle Valve to Absorb Surge Pressure in Pneumatic Cushion Cylinder

공압 쿠션 실린더의 충격압 흡수를 위한 스프링형 니들밸브의 동특성에 관한 연구

The purpose of this study is to find the effective dynamic characteristics of an improved pneumatic cushion cylinder with a spring type needle valve. The dynamic model represented the peak pressure control method when the pneumatic cushion cylinder is moving forward or backward in the horizontal direction. It was found from the simulation results that the peak pressure in the cushion chamber is affected by the spring, which helps to understand the performance of the pneumatic cushion cylinder and to improve or design a better cushion needle valve component. From the simulation results, the stability of pneumatic cushion cylinder with a spring type needle valve was superior and its cushion capability was also better than that without the spring.
