Investigation of the influence of friction pairs geometrical parameters of wagon truck spring - frictional set on the effectiveness of their operation

Abstract

The article gives an account of the results of the analytical and numerical modeling of force action of friction pairs “truck bolster – frictional wedge” and “frictional wedge – frictional plank”. There have been obtained formulas for determining con-straint reactions according to friction pairs geometrical parameters which makes it possible to find their rational values.
