为探究滑靴型面动态变化对受流器通过接触轨端部弯头时振动冲击的影响，根据实测受流器参数和端部弯头标准，建立受流器-接触轨端部弯头耦合动力学模型，设置服役里程0、2×104、4×104、6×104 km四种滑靴磨耗型面，研究了1∶40、1∶50、1∶60、1∶70四种坡度端部弯头和60、80、100 km/h三种运行速度下滑靴型面演变对受流器通过接触轨端部弯头时垂向位移、垂向接触力、垂向振动加速度和离线时间的影响规律。结果表明：在同一弯头坡度和运行速度下，滑靴型面演变对入轨动态性能影响较小，对直线轨和离轨影响较大；减小弯头坡度和运行速度，能有效缓解滑靴型面演变对受流器通过直线轨和离轨时动态冲击的影响程度。
Abstract：To investigate the influence of dynamic changes in the sliding boot profile on the vibration and impact of the current collector passing through the contact rail end elbow, a coupled dynamic model of the current collector-contact rail end elbow was established based on measured elbow collector parameters and end elbow standards. Four types of sliding boot wear profile were set up with service mileage of 0, 2 × 104 km, 4 × 104 km, and 6 × 104 km. The influence of the evolution of sliding boot profile on the vertical displacement, vertical contact force, vertical vibration acceleration, and offline time of the current collector passing through the contact rail end elbow was studied for four slope end elbow of 1∶40, 1∶50, 1∶60, and 1∶70 and three operating speeds of 60 km/h, 80 km/h, and 100 km/h. The results show that under the same elbow slope and operating speed, the evolution of the sliding boot profile has a relatively small impact on the dynamic performance of the track entry, but has a greater impact on the straight and off track. Reducing the elbow slope and operating speed can effectively alleviate the impact of the evolution of the sliding boot profile on the dynamic impact of the current collector passing through the straight track and off track.
