Analytical and experimental investigation of vertical vibration of a freight wagon in the presence of mechanical asymmetry
Result description
Production and construction asymmetry of railway vehicles in the pres- ence of multiple track irregularities on the rail influences the time flow of the wheel. It has an influence on wheel and rail wear defects, especially on driving safety. Pro- duction and construction asymmetry was found during the experimental investigation of the basic parameters of mechanical properties of a double-axel freight wagon type Smmps. This was an impulse for a systematic investigation of the influence of pro- duction and construction asymmetry on the vertical dynamic of complex mechanical systems, such as a railway vehicle. The current contribution introduces a methodol- ogy of analytical solution of the influence of production and construction asymmetry on the vertical dynamic response of a double-axel freight wagon in the presence of multiple track irregularities. Measured field data were used to validate the model.
