A Study on Deflection Angle Fault Detection of Railroad Wagon Bogies
The study adopts contour positioning and angular characterization to construct geometrical models of bogie contour and its front and rear locking plates,and then uses the forensic techniques of truncated features and shape templates to carry out fault inspection of railroad wagon bogies.Experimental analysis of the results of the use of truncated features of the 5 × 5 sliding window for more than 10 ° of the fault angle has the effectiveness of the shape of the template for more than 5 ° of the angle of the identification method has the feasibility of continuing to test the locking plate of the wagon and compare the results of the experiments,resulting in the use of the shape of the template of the fault inspection method of the correct rate of 96.07％,the average detection time of 0.07s,to meet the deflection angle of the Fault detection of real-time,accurate requirements.
