Optimal design and experimental research of railway wheels with constrained damping treatment

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Theoretical model of symmetrical constrained damping structure for railway wheel is established based on complex stiffness method. Four parameters are related to the noise-restraint performance of wheel with damping treatment, which are the thickness of constrained layer, the thickness of damping layer, the loss factor and the complex shear module of damping material. Optimal calculation in the frequency range of railway curve squeal noise is finished. TWINS model is used here to predict the sound pressure level of noise radiated by damping wheel, and comparison between theoretical and experimental results is finished, which indicate the noise radiated from wheel and whole structure can be reduced with 6.6dB(A) and 3.9dB(A).
