| Popis: |
The paper provides main methods for determining stress-strain condition of interaction of a wheel and a brake shoe of the railway rolling stock. It also shows the possibility of using the plain elastic problem. The authors have analysed the peculiarities of a method for studying stress-strain condition in contact zone based on known statements of classic elasticity theory. They have carried out calculations of stress components by analytic method, have studied the influence of normal and shear forces on stress-strain condition in contact zone and have presented the danger of tension stresses. The gained results confirm the significant influence of friction on the decrease of contact and fatigue life of samples and will be useful for forecasting the failure onset of the rolling stock wheel or rail at their interaction. |
