接触器触头弹跳行为规律分析及算法优化

为了得到交流接触器触头弹跳行为规律,从机械振动角度出发,建立了触头弹跳运动微分方程并进行了求解,通过ADAMS/View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相结合,并选择相应的机械参数作为设计变量,对接触器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,验证了遗传算法与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.

Analysis and algorithm optimization of contact bounce behavior of contactors

In order to better understand the contact bounce behavior of AC contactors, a differential equation of contact bounce motion was established and solved from the perspective of mechanical vibration. Through Adams/View AC contactor prototype model, the design of the contact system was optimized by combining the user-defined improved genetic algorithm with dynamic analysis software, and the corresponding mechanical parameters were selected as design variables. The results show that the contact bounce time and maximum displacement were reduced by 89% and 93%, respectively. Finally, the experimental results and simulation errors of the laser rangefinder were less than 2%, which verified the superiority and feasibility of the optimal design method that combined the genetic algorithm with ADAMS software in contactor parameter optimization.
