摘要：

In order to improve the transient response performance in liquid filling rate control of hydrodynamic retarders, a dynamic model of proportional solenoid valve was established and verified with experiment data. Optimal Euler hypercube DOE method was used to analyze the sensitivity of typical parameters to determine the influence of the valve's parameters on output pressure characteristics. The results show that the diameter of the spool is most influential to the pressure overshoot of the proportional solenoid valve, and the cross term of equivalent mass and preload come next. The analysis results provide a certain guiding for the proportional solenoid valve's output characteristic experiment verification and the precision control of the parts in the machining process. Multi-objective genetic algorithm is used to optimize the parameters and obtain corresponding Pareto optimal solution. Compared with initial design point, optimized design point can make the pressure overshoot decreased sharply with a maximum drop of 72% when the response time of proportional solenoid valve remains constant. It can effectively improve the transient pressure control characteristics of the proportional solenoid valve for hydrodynamic retarder. © 2019, Editorial Department of Transaction of Beijing Institute of Technology.
