RAIL CORRUGATIONS AS RESONANCE EFFECT WITH SPEED-DEPENDENT FREQUENCY SPLITTING OF WHEEL FLEXURAL OSCILLATIONS, AND NON-LINEAR CONTACT FORCES BETWEEN WHEEL AND RAIL

For more than eighty years the world-wide problem of corrugated rails has produced hundreds of experts' contributions in the railway literature. In West Germany the problem was recently taken up in the Ministry of Research and Technology programme, "Research into the limits of the wheel/rail system", since high train speeds on corrugated rails cause an unacceptable nuisance. In previous articles in this journal, the author indicated the probable cause of rail/wheel corrugations as self-excited ultrasonic waves interacting with audio-frequency wheel vibrations. Now he presents a new theory which, on the one hand, correctly gives the known average corrugation spacing of 4 to 5 cm, and on the other hand permits interpretation of certain fluctuations in the spacings between successive corrugations, and also known relationships between corrugations and operating conditions.
