摘要:为揭示衔铁偏心作用的影响机制，采用场路耦合方法建立了高速电磁阀多物理场耦合数值仿真模型，并通过试验验证了仿真模型的准确性。然后分析了衔铁中心偏移和偏转对高速电磁阀动态响应特性的影响。结果表明：衔铁中心偏移对动态响应特性的影响不明显，而中心偏转对动态响应特性具有较大影响，且对吸合响应时间的影响大于对释放响应时间的影响；中心偏转角度从0°增大到0.2°，吸合响应时间增加了19.37%，释放响应时间减少了11.35%。
Abstract:In order to reveal the influence mechanism of armature eccentricity， a multi-physical coupling numerical simulation model of high-speed solenoid valve was established by using the field-circuit coupled method， and its accuracy was verified by experiments. An analysis on the effects of armature center offset and deflection on the dynamic response characteristics of the high-speed solenoid valve was conducted. The results show that the armature center offset exerts a negligible effect on the dynamic response， whereas the armature center deflection markedly influences the dynamic response， particularly affecting the suction response time more significantly than the release response time. When the center deflection angle is increased from 0° to 0.2°， the suction response time is increased by 19.37%， and the release response time is reduced by 11.35%.
