CARRIAGE AND RAILCAR BOGIES: THEIR DESIGN AND DEVELOPMENT--IV

Design factors considered in this part include brake ratios; axle fatigue; adhesion, and P.D. More effective braking will require ratios 1:1.5 to 2.2 of the tare weight, cut back to 0.8 at lower speeds. A routine method of axle fatigue calculation indicating the influence of such design variables as fillet radii, type of vehicle, speeds, whether four-wheeler or bogie, and so on, relating to dynamic load allowance and other factors is long overdue. Adhesion improvement through truck linkage to the body at low level requires care that bogie pitching will not cause high stress peaks at the kingpin or cause intense shuttle of the body.
