The lumped parameter approach has been utilized to develop a mathematical model for a pneumatic pressure relay valve for train brake system in order to facilitate theoretical investigation of the static and dynamic characteristics of this valve. The equations of motion exhibit the property known as stiffness. Numerical techniques for the solution of these equations are discussed. Theoretical results show good correlation with experimental results. The mathematical model has been utilized to investigate the effects of parameter variations on output pressure response. It has been found that for stable performance of this relay valve, it is essential that the feedback orifice be properly sized in relation to the input orifice.
