Abstract

This paper is dedicated to investigate the static and dynamic behavior of a pilot operated pressure reducing valve (PRV). The valve is the main component in an Anti-skid braking system of a vehicle. This system is fed by the hydraulic power from a constant pressure source. A mathematical model is deduced for the valve. A simulation program is developed using
the MATLAB-SIMULINK where the mathematical model is implemented in the program. The developed program is used to study the dynamic valve response due to different input displacement values and effect of varying different design parameters on the overall performance of valve. A conclusion is made to evaluate the valve response and recommendations are suggested to improve valve performance.
