Abstract:
A vehicle roof panel that is tunable with respect to the occurrence of vibration and the resonant frequency of vibration is provided. A frequency gain associated with the vehicle roof panel has been determined to be a function of the ratio between the width of roof beads impressed upon a roof panel and a gap between adjacent roof beads. When the ratio is between approximately 0.5 and 4.7, the frequency gain associated with the vehicle roof linearly follows values of the ratio. Accordingly, varying the width of the roof beads and/or the gap between adjacent roof beads such that the ratio remains between approximately 0.5 and 4.7, results in the vehicle roof panel being tunable.
