Abstract：The static characteristics of the series brake valve are applied to evaluate the relationship between the output pressure of an air-brake system and the brake stroke during the state of braking balance. The effect of the structural on static characteristics was analyzed by a parameter model based on the AMEsim. A static response process of the series brake valve was built both by its industry standards and the working principle of the linear load system in a simulation environment. In order to reproduce the response process under braking state, a measurement system of static characteristics for the series brake valve was designed by LabVIEW platform utilizing a high-accuracy data acquisition system. Both the MSA and comparative analytical method were introduced to verify the reliability of the system. The experimental result show that the measurement ability index Cg is less than 1.67, and system accuracy indexes are less than 30%, which meet the acceptance requirements of new equipment.
