Application of AMESim® & CFX®-based technique to the valve behavior characteristics of regulator for hydraulic winch

The hydraulic equipments using hydraulic fluid have higher power outputs than those of other systems, which is why they have long been used for automation in construction and machinery industry. Among the hydraulic equipments, the regulator used in the hydraulic winch, which is an item of the deck machinery, is one of the important parts that can improve the efficiency and the output in the hydraulic winch system. Our research defines a parameter design of the hydraulic regulator. Using AMESim®, we will conduct 1D Modeling. And by utilizing CFX® which then enables us to use 3D Modeling, our research will analyze a change in pressure of each port resulting from the regulator's spring constant and a change in primary tension-compression field. Our research, then, will analyze an alteration in trait drawn from a change in the interval between spool and sleeve. As indicated by the results of our research, we believe it can be used for design of the regulator used for hydraulic winch in the deck machinery.
