为了得到交流接触器触头弹跳行为规律，本文对接触器运动微分方程进行求解。利用ADAMS/View建立交流接触器样机模型，将用户自定义的改进型遗传算法与动力学分析软件ADAMS相结合，选择相应的机械参数作为设计变量，对触头系统进行优化设计。结果表明：通过遗传算法优化后的触头弹跳时间和最大位移分别降低了89%和93%。最后使用激光测距仪进行的实验结果与仿真误差在2%以下，验证了遗传算法和ADAMS软件相结合的优化设计方法在接触器参数优化问题中的优越性和可行性，研究结果为进一步全面优化接触器样机提供了新方法。

In order to obtain the law of contact bounce, the two degree of freedom piecewise coupled differential equation of contact system is simplified and evaluated. Using ADAMS view to establish the prototype model of AC contactor, combining the user-defined genetic algorithm with the dynamic analysis software ADAMS, selecting the mechanical parameters that have a great impact on the bounce time as the design variables, and optimizing the contact system design. The results show that the bounce time of contactor contact optimized by genetic algorithm is reduced by 89%. Finally, the experimental results and simulation errors of the laser rangefinder are less than 2%. The superiority and feasibility of the optimization design method based on genetic algorithm and ADAMS software in the optimization of contactor parameters are verified. The research results provide a new method for further comprehensive optimization of contactor prototype.
