Abstract
The present disclosure is related to reducing shake and vibration in Head-Up Displays (HUDs) under dynamic operating conditions. The apparatus includes a curved mirror for projecting an image from a display unit on a windshield of a vehicle. The curved mirror has damping tape on its nonreflective side to absorb vibrational energy and shift the first natural frequency of the curved mirror to a higher frequency. The damping tape includes at least a viscoelastic adhesive layer and a constraining layer. The method for stabilizing the HUD includes applying damping tape selected and positioned to reduce vibrational amplitude and shift the first natural frequency of the curved mirror to a higher frequency.
