摘　　要：将接触线与受电弓滑板的磨耗型面进行离散化处理,以接触线在不同横移条件下与受电弓滑板磨耗型面的共形度为目标,建立受电弓滑板磨耗累积速率的非线性规划数学模型;采用果蝇算法对该数学模型进行收敛性分析,验证了算法的有效性;对受电弓滑板在不同运行速度和不同接触力作用下磨耗累积量和磨耗变化速率方面进行了仿真分析。研究表明:所提出的优化磨耗型面模型可以有效地延长受电弓滑板的使用寿命,为受电弓滑板型面的优化设计和弓网磨耗的预测提供一种方法和依据。Contact line and the wear surface of the pantograph slide are discretized.Nonlinear programming mathematical model of the cumulative wear rate of the pantograph sliding plate is established,aiming at the conformal degree of the contact line and the wear surface of the pantograph sliding plate under different transverse movement conditions.Fruit flies algorithm was used to analyze the convergence of the mathematical model,and the validity of the algorithm was verified.Running speed of the pantograph slide under the action of different running speeds and different contact forces and the wear cumulant and wear change rate are simulated and analyzed.The result shows that the proposed model can effectively extend the service life of pantograph slide,and provide a method and basis for the optimization design of pantograph slide and the prediction of pantograph-catenary wear.
