摘　　要：高压水射流作为一种绿色、高效的清洁技术,已经被广泛地应用于轨道清洁。为了获得高压水射流对槽型轨轨面的最佳清洗效果,利用计算流体动力学(CFD)分析软件FLUENT,对水射流的清洗过程进行了模拟仿真。依据仿真结果分析了轨道面的受力与水射流的流动情况,并对水射流的入射角与靶距进行了优化分析,最后得出在指定的条件下,射流的最佳靶距为10~15cm,最佳入射角为25°。High pressure water jet as a green,clean and efficient technology,has been widely used in track cleaning.In order to obtain the best cleaning effect of high pressure water jet on groove track surface,the computational fluid dynamics(CFD)analysis software FLUENT was used to simulate the process of water jet cleaning.According to the simulation results,the force of the track surface and the flow of water jet were analyzed,and the angle of incidence and the distance of the water jet were optimized.Finally,the optimum target distance of the jet is 10~15 cm and the best angle of incidence is 45 degrees under the specified condition.
