Abstract:
1. A sealing strip configured to be positioned between a vehicle bodywork and glazing and constituting an acoustic damping means when subjected to action of a vibrational field, wherein the strip works in shear combined with movements of the glazing in the plane of the glazing at the location of the strip, while the bodywork deforms in the direction normal to the glazing at the location of the strip, wherein the work of the strip in shear is defined by a Q factor of the strip, the Q factor being less than or equal to 4 and determined by a ratio of a maximum receptance of the strip to a shear-mode quasi-static receptance of the strip, the receptance of the strip being a frequency response function that gives rise to a ratio of a frequency-dependent displacement of a weight to a force applied to the weight, the weight being mounted between two metal supports by specimens of the strip.
