The spool valve port has a variety of structural forms, the calculation of the flow area and hydraulic diameter is tedious, and its modeling and simulation is complicated. In the AMESim simulation environment, these problems can be better solved, but the related literature is relatively small and there is no detailed explanation. This study combined previous research results to analyze the model of the circumferential opening, the common non circumferential opening, the combined notch, and the profile of the typical notch slide valve port, and the modeling method of the different forms of valve port in the AMESim simulation environment was described in detail.Taking the multi way valve of construction machinery as an example, the AMESim simulation model was established. For the profiled notch of main spool, the AMESim and MATLAB joint simulation method was adopted. Through the simulation analysis, and compared with the control valve sample, the flow characteristic curve was basically the same, which accords with the requirements of modeling and simulation. The purpose of this study is to provide some reference for the design of hydraulic slide valve and analysis the dynamic characteristics of the system.
