摘要
为提高增压装置电磁阀的静态与动态特性,实现超高压共轨系统精确灵活的控制,建立了电磁阀静态与动态特性三维模型,对电磁阀进行了多参数优化设计,获取了最佳参数组合,并在此基础上开展了参数优化后电磁阀特性试验。仿真结果表明:优化后的电磁阀性能比优化前得到了提升;随着驱动电流的增大,对应的静态电磁力逐步增大;随着弹簧刚度的增大,电磁阀开启响应时间延长,但关闭响应时间缩短;在三种不同的弹簧刚度下,电磁阀开启响应时间均小于0.5 ms,满足增压装置对电磁阀静态与动态特性的使用需求。
In order to improve the static and dynamic characteristics of the solenoid valve in pressure-amplifier device,and to realize the precise and flexible control of the ultra high pressure common rail system,the static and dynamic characteristics of three-dimensional model of solenoid valve were established,and the multi-parameter optimization design of solenoid valve was carried out,whereby the best parameter combination was obtained.On this basis,the experimental research on the characteristics of solenoid valve after parameter optimization was carried out.The simulation result shows that with the increase of driving current,the corresponding static electromagnetic force increases gradually,and that with the increase of spring stiffness,the opening response time of solenoid valve increases whereas the closing response time shortens.At the same time,under three different levels of spring stiffness,the opening response time of the solenoid valve is less than 0.5 ms respectively,which meets the demand of the pressure-amplifier device for the static and dynamic characteristics of the solenoid valve.So the performance of optimized solenoid valve is improved compared with that before optimization.
