Dynamic simulation analysis of constant speed valve based on AMESim

The working principle of the constant speed valve was introduced, and the static characteristics of the constant speed valve were analyzed through the establishment of a mathematical model. The modeling and simulation of the constant speed valve were carried out using AMESim software. The influence of inlet pressure on the dynamic response of constant speed valve is analyzed. And by changing the main spring stiffness of the constant speed valve, the size of the oil outlet, the area of the fixed orifice, the outer diameter of the valve core and other structural parameters, the influence on the performance of the constant speed valve is analyzed. It provides a basis for further improving the dynamic characteristics and design optimization of the constant speed valve.
