Wheel weight characteristics of bogie with air spring height difference

초록

When considering the development of railway safety technology for a train, lots of innovative and delicate techniques such as using ultrasonic waves, and infrared light have been developed [1,2]. In spite of the good performance, they are limited to broadly use by their complexity to operate, a long inspection time owing to the disintegration of a train, and an operation cost. Thus, the most promising technique is the method to evaluate the change of the wheel weight, which is simple and effective to find the abnormal bogie or train for the close inspection.
