为优化柴油机高速电磁阀设计参数及提高其工作效率,建立高速电磁阀静态吸附特性和动态响应特性模型;采用Visual Basic 7.0和MATLAB相结合的方法研发柴油机高速电磁阀特性仿真系统,并对设计参数优化与特性进行仿真分析。研究结果表明:采用自适应变尺度混沌优化算法可实现柴油机高速电磁阀设计参数优化和工作效率提高;当工作电流为10 A时,所产生的最大电磁吸附力能够确保柴油机高速电磁阀正常开启稳定;当工作气隙宽度为50μm时,能够有效缩短柴油机高速电磁阀的静态响应时间;当弹簧预紧力为80 N左右时,可确保其工作开启和关闭的响应时间满足实际要求,而衔铁质量对柴油机高速电磁阀动态响应影响不大。

In order to ensure that the design parameters of high-speed solenoid valve in diesel engine was optimized and its work efficiency was improved,the characteristics models of static suction and dynamic response to high-speed solenoid valve were established.A characteristic simulation system of high-speed solenoid valve was developed by using Visual Basic 7.0 and MATLAB and the optimization of design parameters and characteristic simulation analysis were processed on high speed solenoid valve.The results show that optimization on design parameters of high-speed solenoid valve in diesel engine and improvement on work efficiency can be realized with adaptive mutative scale chaos optimization algorithm.Furthermore,there is enough suction power produced to ensure that high-speed solenoid valve can be started normally and stably when the work current is 10 A,the static response time can be shortened effectively when the width of air gap is about 50 μm,the practical requirements for the response time of starting and shutting for high speed solenoid valve can be satisfied when the spring preload is about 80 N,but there is little effect on dynamic response from the armature mass in diesel high-speed solenoid valve.
