摘要：

The conditions necessary for the existence in the British Rail system of corrugations in the 40-80 mm range have been investigated with particular reference to track structure, friction and locomotive traction characteristics. Two oscillators are identified. The first consists of a clamped length of elastic rail which gives rise to corrugations in the range 38-48 mm under frictional excitation. The second oscillator consists of two sleeper masses interconnected by springs provided by the elastic action of lengths of rail equal to the sleeper spacing. Excitation of the oscillator gives a corrugation range of 70-89 mm. The two oscillators cover an overall corrugation range of 38-89 mm, which is in substantial agreement with British Rail observations.
