LATERAL FORCE DURING CURVE NEGOTIATION OF FORCED STEERING BOGIES

To shorten the travel time of limited express trains between Sapporo and Kusiro in Japan, a tilted diesel car with forced steering bogies has been developed to cope with the many small radius curves common to the narrow gauge railways in Japan. This paper compares the forced steering with the conventional bogie and describes the influence of steering quantity on the lateral force of the forced steering bogie in negotiating curves based on computer simulations and field tests. Tests showed that the forced steering bogie can reduce lateral forces between wheel and rail, but this reduction should be studied on transition curves as well. The lateral force of the first wheelset is the largest. To decrease the lateral force more effectively, the steering ratio is set at 35% higher than the value that makes the rail position. The running stability is satisfactory at field tests of 140 km/h. Details of steering mechanism and computer simulations are given.
