The principles and results of a series of experimental investigations into the stability of acoustic contact during the high-speed ultrasonic testing of rails are presented, together with formulas for calculating the trajectory of the search head on passing over an isolated rough portion of rail as a function of the velocity of the search head and the parameters of the suspension. In order to increase the service life of the search head it is recommended that an automated system of compression should be provided.
