ACOUSTICALLY OPTIMAL DESIGN OF RAILWAY WHEELS
The squealing noise of railway wheels during the passage through curves is an important subject in the field of sound radiation in street-traffic. Measurements and frequency analysis show that this squealing noise is caused by the bending vibrations of the wheel disk excited by stick-slip between the wheel rim and the rail. Consequently from the acoustical point of view in the design of railway wheels it is of importance to know the coherence between the constructional parameters of the wheel disk and its acoustical quantities. In the present study the radiated sound pressure and power of a wheel disk due to axial harmonic excitation at one point at the ric is calculated. On the basis of the subjective human feeling of sound pressure the radiated sound power, quality factors for the various types of wheel disks are specified.
