Finite Element Simulation and Optimization Design of the Parameters of Vibration Reduction for Damped Wheels
摘要
Abstract
In order to effectively suppress wheel vibration noise and make up for the deficiencies of field tests, the vibration reduction performance and optimal design of damped wheels are studied. Based on the damping mechanism of viscoelastic damping materials, this study takes the damped S1002CN high-speed EMU wheels as the object. The finite element model of the damped wheels is established and simulated by means of ABAQUS software. Combining the results of simulation with the orthogonal design, the sequence and significance of the three main structural parameters of the damped wheels influencing the radical vibration acceleration reduction rate of the wheel tread are analyzed. On this basis, the optimal combination of these parameters can be determined quickly as follows:4 mm damping layer thickness, 1.5 mm constraint layer thickness and attaching the constraint damping layers on both sides of the wheel. The research suggests that the viscoelastic constrained damping technology is an effective measure to restrain wheel high-frequency vibration, which may have great theoretical and practical values for the application of viscoelastic damping materials to low noise wheels.关键词
