BODY ROLLING AS INFLUENCED BY BOGIE SUSPENSION--1

Considerations of design variables affecting the angle of roll of bogie vehicles is discussed. A standard Russian coach bogie with divided bolster swing links is shown. Tests carried out with modern coaches running through curves at a steady speed resulting in an unbalanced lateral force equivalent to 0.1 g show that the angular displacement varies between 0.019 and 0.032 radians. With some modern bogie locomotives using laminated bolster springs and operating at speeds of up to 90 mph the angle of roll on straight track was found not to exceed about 0.005 radians. Roll stiffness of coaches, railcars, diesel and electric locomotive bogie suspensions for British Railways stock and the angle of roll are tabulated.
