“…e contact between the pantograph sliding plate and the catenary conductor is becoming more and more unstable, and the occurrence frequency of the arcing phenomenon increases immediately [16,17]. ere are many reasons for arcing phenomenon, such as too small pantograph catenary contact pressure, too large amplitude of vertical vibration of pantograph sliding plate, and poor smoothness and hard points of catenary line.…”

With the rapid development of high-speed rail in China, addressing the issue of safety assurance during the operation of the train is very important. A very important part of a train’s power supply system is the pantograph and catenary system, which consists of a pantograph and a catenary. Failure of the pantograph-catenary system can cause significant damage to the normal operation of the train. The dynamic performance of the pantograph-catheter system must be detected in real time during the operation of the train. This paper is based on the study and analysis of pantograph-catheter dynamic performance parameters and developed a system for real-time detection of pantograph-catheter dynamic performance parameters based on a car visual system. The results are as follows: based on this detection method, the visual error is low and the accuracy is high. The machine-based directional height detection module developed in this paper has a good detection effect and high test accuracy; the arcing detection module designed in this paper can effectively detect the arcing and store the arcing pictures and can display the duration of single arcing and the arcing rate of the section in real-time. The practical application effect is good. The results show that the focal length of the camera lens is 16 mm, and the error of the machine vision system is low. The system designed in this paper may make a great contribution to the operation condition monitoring and fault diagnosis of the pantograph-catenary system of a high-speed train in the future.

“…The irregularity of track is widely used in the research of straddle type monorail, these studies have used irregularity of road or rail, but no one discussed why and whether it is appropriate. Zhou J. et al [17,18], Wen X. et al [19], Du Z. et al [20][21][22] studied the traction performance, curve passing performance, stability; structural strength safety and comfort of straddle type monorail train under the excitation of A-level road roughness.

The dynamic performance of straddle monorail train is closely related to the track irregularity. However, there is little research on the track irregularity of straddle monorail , and its semi-random particularity makes it impossible to use the existing track spectrum. In this paper, the irregularity of the running surface of prestressed concrete (PC) beam of monorail is measured, the altitude map is drawn, and the expression of the random irregularity of the track is obtained; the irregularity of finger-band and the deflection of PC beam under dead load are studied; a method is proposed to descript the semi-random track irregularity of straddle type monorail, the running surface of straddle monorail is reconstructed, and the correctness is verified by comparing with the test.
