Abstract:

滑动电接触是一个具有耦合作用的特殊摩擦副,其中接触电阻和磨耗率是影响接触状态的重要因素。确定接触载荷的数值,使得两个目标最小是本文研究的重点。通过滑动电接触实验,分析了接触电阻和磨耗率存在的相互冲突、矛盾关系,描述了此种多目标问题的Pareto解。并得到了接触电阻和磨耗率为输出,运行速度、接触载流以及载荷为输入的变化数据。进而对其进行了实验数据的Pareto解分布分析,训练了相应的神经网络黑箱模型,依此设计了应用于多目标的人工鱼群优化算法,并进行了测试函数检验,得到了较好效果。最后利用该算法对所建立神经网络模型进行接触载荷的优化,得到了相应工况下最优接触载荷的数值,对结果进行了分析,表明了算法的有效性。
