The objectives of designing the charging valve in full power braking system with accumulator are to improve the charging efficiency, decrease the manufacturing cost and the influence on other systems of the vehicle. According to the performance analysis of the system, a dynamic mathematical model for robust design of charging valve and analyzing its charging characteristics was established. Experiments were conducted to verify the simulating model. On the basis of analyzing various factors that affected the charging characteristics of the system, the design variables and the uncertainty factors of charging valve were conducted. Based on the charging time of the system, the results of the simulation were used to make the robust design of charging valve. The results of the robust design indicated that the reasonable design parameters could decrease the machining precision and improve the charging efficiency and robust performance.
