| 摘 要： | 脱附电磁阀是汽油轿车燃油蒸发控制系统中关键零部件之一,电磁阀的动态响应特性对燃油蒸汽的脱附速率有着重要的影响,同时,电磁阀衔铁的撞击噪声和电磁阀的通电可靠性与电磁阀产品的性能也有重要关系。为此,首先针对脱附电磁阀进行适当的模型简化,采用电磁场模拟软件Maxwell建立数学模型,通过仿真手段与试验结果进行响应特性标定对比,从而验证数学模型的准确性。而后基于正交设计方法,研究了不同铁芯材料、线圈匝数、线圈直径、工作间隙以及衔铁质量等结构参数对电磁阀的动态响应特性、撞击噪声以及能耗量的影响,并进行电磁阀综合性能的最优化设计,获得了最佳的综合性能。最后通过试验手段对最优化方案进行验证,并对其撞击噪声、响应特性进行了分析,结果表明通过正交设计方法的模拟预测与试验数据有较高的一致性,从而为电磁阀的综合优化提供了可靠的方法。

| Abstract: | The rapid prosperity of automotive market in China poses serious environmental problems. Therefore, combustion emissions such as NOx and soot draw much attention in recent years. However, in addition to them, fuel evaporation emissions account for large proportion of pollution from automobiles. The fuel evaporation control system in the gasoline engine vehicle effectively inhibits the fuel vapor emission, which is beneficial to both pollution reduction and improvement of heat efficiency. Solenoid valve is one of the key parts in the fuel evaporation control system. It can accurately control the mass of gasoline vapor which strip out from the carbon canister by opening or closing the solenoid valve and ensure the smooth operation of the gasoline engine. Dynamic response characteristics of the solenoid valve have an important influence on the capacity of inhaling gasoline vapor into the intake manifold, thereby it attracts much attention. Actually, due to advantages such as structural simplicity, rapid action, low manufacturing cost and low energy consumption, solenoid valves are widely used in machinery, vehicle, aerospace and other industries. The effects of coil number of turns, wire diameter, core materials and armature mass on the response behavior, impact noise and energy consumption were explored by means of the software Ansoft Maxwell and orthogonal design method. Finally, optimization on the integrated performance of the solenoid valve was achieved to get the best comprehensive performance. |
