Abstract
The parameters that could influence the vibration and noise levels are always a concern for noise control engineers. The Finite Element Method (FEM) and Boundary Element Method (BEM) will be used to examine ribbed effect, plate thickness (t), material density (ρ), Young's modulus (E) and modal damping (ζ) on noise contributions. A model updating process that compares the calculated results in modal frequencies and mode shapes to the test results (from a modal testing) will increase the accuracy of the FEM model. This improved model will be used for evaluating/validating the noise response of motorcycle transmission top covers.
