Determination of natural frequencies and vibration amplitude of a class 143 railbus wheelset by theoretical and experimental methods (TM-EST-045)

During track tests to investigate the problem of cracks forming from holes in the webs of Class 143 Railbus wheels, DM & EE measured high strains at a frequency of 520 Hz when the vehicle was travelling on curves. Class 143 Railbuses produce a squealing noise when curving and analysis...
