In order to study the coupling relationship between structure parameter and response time of high speed solenoid valve(HSV) for common rail injector and improve the dynamic response speed of HSV by the optimized design of structure parameter, Ansoft and Simplorer softwares were adopted to conduct joint simulation, and the dynamic response calculation model of HSV coupled with driving circuit was established.

The accuracy of the calculation model was verified by the test data. Based on the sample matrix provided by the calculation model, Doptimal design and least square method were considered, and the RSM mathematical approximation model was then used to establish a response surface prediction model for HSV response time in order to reduce the computing time in exploring the coupling relationship between optimization parameter and objective. Five parameters including coil turns, armature lift, outer magnetic pole area, inner magnetic pole area and armature radius were selected as the planned optimization structure parameters, the sensitivity analysis of planned optimization structure parameters was carried out, and the armature lift was determined as the sensitive parameter of opening response time. Finally, the structure parameters were optimized to improve the response speed of HSV by NBIAFSQP optimization algorithm. The optimization results shows that the opening, closing and total response times of HSV reduce by 6.25%, 9.56%, and 7.64% respectively, and the dynamic response speed of HSV is hence improved.tion model was then used to establish a response surface prediction model for HSV response time in order to reduce the computing time in exploring the coupling relationship between optimization parameter and objective.
