Snakelike motion detection and analysis system of high-speed-train bogie and method thereof

Abstract

The invention discloses a snakelike motion detection and analysis system of a high-speed-train bogie and a method thereof. The system aims at analyzing the snakelike motion state of the high-speed-train bogie in different environments and different work conditions and reasons for generation of the snakelike motion and effects of the snakelike motion on operation security of the high-speed train. Bogie transverse and longitudinal acceleration signals are acquired through a transverse two-dimension acceleration sensor and a longitudinal two-dimension acceleration sensor, which are arranged on the bogie of the system and storage of characteristic data is performed through filtering of the signals by a real-time data acquisition controller and the analysis result and trend are transmitted to a train display terminal through a train transmission network. Therefore, long-term tracking and trend analysis of the bogie transverse and longitudinal data are realized and occurred faults of the bogie are monitored and alarmed in a real-time manner.

Description

technical field [0001] The invention relates to a bogie detection and analysis system and method thereof in the field of railway locomotives, in particular to a high-speed train bogie serpentine motion detection and analysis system and method thereof. Background technique [0002] When the bogie runs at a high speed on a straight road, abnormal lateral vibration will occur, and the amplitude of the vibration will continue to expand with time, and in severe cases, it will cause serpentine motion instability. The bogie serpentine instability will affect the driving safety of high-speed trains, and effective detection and analysis should be carried out on the bogie serpentine instability. [0003] The existing bogie serpentine instability monitoring technology is: collect the lateral acceleration signal of the bogie through a lateral two-dimensional acceleration sensor arranged on the bogie, and then filter the signal through the real-time data acquisition controller through th...

AI Technical Summary

Problems solved by technology

[0006] This method can only calculate and alarm the lateral acceleration value, but does not store, display and analyze the lateral acceleration value, and cannot conduct relevant data analysis on the specific working conditions and severity of the serpentine instability of the bogie, so it cannot be studied The essential cause of its serpentine instability

[0007] This method can only monitor the lateral acceleration of the front and rear sides of the bogie, but cannot monitor the longitudinal acceleration, and cannot understand the sway of the bogie during operation
