摘要
弓网系统中,接触压力的大小直接影响列车的受流稳定性和滑板、接触网导线的使用寿命。本文通过浸金属碳滑板与铜导线的对磨实验,分析了不同载流、速度以及变化压力情况下的滑板受流和磨损情况,通过数据拟合建立电流相对稳定系数、磨损率与电流、速度和压力的预测模型,由于磨损率与电流相对稳定系数存在彼此冲突的矛盾关系,因此应用设计的多目标粒子群算法求解电流相对稳定系数和磨损率的Pareto最优前沿解,最后通过基于信噪比的多目标决策方法确定基于电流稳定性相对最好、磨损率相对最小情况下的最优压力载荷,为电力机车的实际运行调整压力载荷提供理论基础。
In pantograph catenary system, contact load directly influences the current-receiving stability and the service life of the slide and wire of the train. In this paper, through leaching copper carbon slide and copper wire of the friction pair of grinding experiment, analyzes current-receiving and wear of the different current, speed and load and through data fitting to establish prediction model of current relative stability coefficient and wear rate and current, velocity and load, because wear rate and current relative stability coefficient exist contradictory between each other, so applied the multi-objective particle swarm algorithm to solve current relative stability coefficient and wear rate of Pareto optimal front solution. Finally through based on signal to noise ratio of the multi-objective decision method to determine the optimal load based on the stability of current best and wear rate under the condition of relative minimum, for electric locomotive operation adjustment load provide theoretical foundation.
