摘要： 为提高高速电磁开关阀非线性模型的仿真计算速度，采用能量法模型简化策略简化电磁阀模型.针对电磁阀多域作用相耦合的特点，在能量法评价指标的基础上提出子系统活跃指数概念，评价电磁阀各域作用在系统动态过程中的重要性.在Matlab/Simulink中建立电磁阀数学模型并简化.台架实验表明，该物理模型及其简化模型的计算误差均在预设的±5%以内.

Abstract: To reduce the complexity and increase the calculation speed for nonlinear model of high speed onoff solenoid valve, the energybased model reduction algorithm was used. Considering the multidomain coupling characteristic, the concept of subsystem activity index (SAI) was proposed to evaluate the contribution of the subsystems. The full model was established and reduced in Matlab/Simulink environment and validated by a testbench experiment. With the error less than ±5%, the model built in this paper is accurate for further study.
