Abstract

This paper concerns mathematical modelling of dynamic performances to a new permanent magnet electromagnetic valve actuator (PMEVA). Both static and transient characteristics were simulated by using the finite element method (FEM) and field-circuit approach. The magnetic force values versus the excitation current and the position of the valve actuator movable part have been determined. Our concept of the mover positioning relative to the radial magnets is quite novel. PMEVA parameters are satisfied for implementation in combustion engines. Transients in the device have also been analyzed for no-load and for the nominal burden of the actuator. The indications of the position sensors and the excitation current waves were simulated and measured for the step voltage supply. The calculation results were verified experimentally, and a good conformity has been observed. The advantages of our actuator are simple construction, short time of the switching, the current supplying being needed only at the runner extreme positions, and simple controlling. Additionally, PMEVA design can be extended to support the simultaneous operation of four valves.

摘要

本文涉及一种新型永磁电磁阀执行器（PMEVA）动态性能的数学建模。通过使用有限元方法（FEM）和场路耦合方法对静态和瞬态特性进行了模拟。确定了磁力值与励磁电流以及阀门执行器可动部件位置的关系。我们提出的动子相对于径向磁体的定位概念相当新颖。PMEVA的参数满足在内燃机中应用的要求。还对该装置在空载和执行器额定负载情况下的瞬态进行了分析。针对阶跃电压供电，模拟并测量了位置传感器的指示和励磁电流波形。计算结果通过实验得到验证，并且观察到了良好的一致性。我们的执行器的优点是结构简单、切换时间短、仅在转轮极端位置需要供电以及控制简单。此外，PMEVA的设计可以扩展以支持四个阀门的同时运行。
