摘　　要：为了全面提高交流接触器的整体性能指标,该文建立了含触头系统与电磁系统的交流接触器全仿真三维动态模型,考虑运动过程中摩擦力、碰撞过程形变等因素的影响,将描述材料形变量的本构方程、运动方程以及边界约束引入控制方程中,建立三维运动数学模型。通过实验对模型进行验证,重点考核铁心与触头的弹跳情况。实验结果表明该三维仿真模型能真实反应交流接触器触头、铁心的吸合弹跳过程。通过仿真模型分析触头一次弹跳、二次弹跳以及铁心弹跳的影响因素,分析了合闸相角、电压、铁心弹簧、触头弹簧等参数对触头、铁心吸合弹跳的影响,为进一步研究交流接触器吸合弹跳抑制措施提供理论依据。In order to improve the overall performance indicators, a 3D dynamic simulation model of alternating current （AC） contactors which includes contact and electromagnetic systems were built. At the meantime, the constitutive equations, motion equations and boundary constraints were introdticed into the control equations for the consideration of influences caused by the friction in motion and the deformation during the bounce. And then, the 3D motion mathematical model was verified through the experiment. The focus is on the bounce of its contact and core. The result shows that the 3D model reflects the actual bounce of the contact and core in the closing process. Moreover, through analyzing the influences of the first and the second bounce of the contact and core by the simulation model, this paper analyzed the influences to the bounce of the contact and core which caused by the close phase angle, voltage, core spring, contact spring and so on. And it provided the theory basis for the further study on the suppression measures of bounce in the closing process.
