Vibration Characteristic Comparative Analysis of Standard Wheels and Damped Wheels

The standard wheel and damped wheel model were established in ANSYS, through modal analysis to study the vibration characteristics of them. The results show that vibration of standard wheel is mainly manifested as torsion pendulum vibration of tread, radial and axial vibration of web and combination vibration of tread and web in frequency of 0～5000Hz.In this frequency range, 0~1000Hz mainly manifested as torsion pendulum vibration of the tread, above 1000Hz, these three have the performance, especially in the web vibration is most active, therefore, Web is the primary noise radiation source in the standard wheel structure. The mode shape of damped wheel is same as standard wheel in the range of 0~5000Hz, mainly manifested as torsion pendulum vibration of tread, radial and axial vibration of web and combination vibration of tread and web.
