초록

Hydraulic system technology is widely used in various fields such as automobiles, agricultural machinery,construction, and manufacturing along with the rapid development of science and technology. Recently, in thehydraulic coupler market, inefficient parts requiring manual connection of a plurality of hydraulic circuits oneby one have been greatly highlighted. In order to solve these inefficient problems, the development of amulti-circuit multi-combination coupler capable of solving a plurality of hydraulic circuits at once hasemerged. In this study, a structural analysis was performed according to the coupling method of themulti-combination hydraulic coupler of 4 circuits and 6 circuits, and it was confirmed that the structuralsafety of the multi-circuit hydraulic coupler meets the conditions in the hydraulic machinery industry byimproving the weak parts through material changes. The points where the maximum stress and strain appearwere identified to analyze ways to increase durability and safety.
