PREVENTION OF SKIDDING ON SHINKANSEN VEHICLES BY IMPROVING FUNDAMENTAL ADHESION WITH SPECIAL COMPOSITE SLIDING BLOCKS ON WHEEL-TREADS

Fundamental adhesion phenomena at speeds to 350 kph were investigated using a high-speed simulator to determine the relationship between slip ratio and traction coefficient. Fundamental adhesion coefficients decreased remarkably under water lubrications with increasing rolling speeds. To improve adhesion under wet conditions and decrease the shelling or flattening of wheel treads with wheel slide, a composition block was developed to clean the wheel tread. Universal adoption of this block on all Shinkansen cars resulted in a remarkable decrease in wheel-slide damage.
