Acoustic Roughness Measurement of Railhead Surface Using an Optimal Sensor Batch Algorithm
Contact and friction between wheel and rail during train operation is the main cause of the rolling noise for which railways are known. Therefore, it is necessary to accurately measure the surface roughness of wheels and rails to monitor railway noise and predict noise around tracks. Conventional sy...
