摘要
在对发动机电磁气门驱动(Electromagnetic Valve Actuation,简称EVA)进行的仿真计算中,采用磁场分割法建立了电磁铁磁路模型,并根据牛顿第二定律和电压平衡原理分别建立了EVA动力学模型和电路模型,编制了相应的计算程序。计算与试验对比基本符合的情况表明,所建模型反映了EVA的基本特征,整套仿真方法可行。
In the simulation of Electromagnetic: Valve Actuation(EVA) , the magnetic circuit model of electromagnet is established based on the magnetic field division. The kinetic model of EVA based on Newton's Second Law and the circuit model based on voltage equation principle are also built. The calculation program is developed with these models. The result of the simulation almost accords with that from the experiment. This demonstrates that the simulation model rightly reflects the feature of the EVA, and the whole simulation method is available.
