EFFECT OF WHEEL FLAT ON THE CAR VIBRATION

A series of running tests was performed with the prototype "B" train for the new Tokaido line. The object is to investigate the effect of the wheel flat on the car body and truck vibration. The data were expected to give a reference for design and maintenance of car, and to give a base for determining the allowable limit of the flat length in practical operation. The running speed was 200 km/h for the flat up to 90 mm, and 50 km/h for 110 mm. So far as the truck and car body vibration is concerned, flat caused more vibration at a low speed than at a high speed. So car vibration is not considered the most decisive factor limiting the allowable length of flat.
