3/8″유압 퀵 커플러의 피스톤형상을 고려한 최적설계에 관한 연구

초록

A hydraulic quick coupler is a component used to easily connect or disconnect pipes or hoses that transferhigh pressure fluid without leakage in various mechanical devices. In this study, to obtain an optimal designof a 3/8" hydraulic quick coupler, the effect of different shapes of the internal piston on the internal flowcharacteristics of the coupler was analyzed and evaluated through numerical analysis based on computationalfluid dynamics. Subsequently, the optimal shape design of the internal piston was obtained by comparing theflow characteristics results such as velocity distribution, temperature distribution, and the pressure drop of thehydraulic quick coupler.
