DEVICE FOR PRODUCING A STRUCTURE-BORNE SOUND VIBRATION IN THE EVENT OF AN IMPACT OF A COLLISION OBJECT WITH A VEHICLE

摘要

The invention relates to a device for producing a structure-borne sound vibration in the event of an impact of a collision object with a vehicle. For this purpose, an element (1a, 1b) that can be vibrated mechanically and a plurality of mechanical excitation elements (2a, 2b) or a preferably continuous excitation profile are arranged relative to each other in such a way that the excitation elements (2a, 2b) or the excitation profile or alternatively the element (1) that can be vibrated are slid mechanically relative to each other by means of an impact of the vehicle, and the excitation elements (2, 2a, 2b) or the excitation profile causes a mechanical excitation of the element (1) that can be vibrated. The sequence of excitations or the continuous excitation thus leads to a significant and measurable structure-borne sound vibration, which signifies the severity and speed of the impact or of the deformation. A particular advantage of this embodiment is that the element that can be vibrated can be reversed, at least in the event of small impact events, and that the device can therefore be reused. If a continuous excitation profile is used, the excitation can be made to have a significantly narrower band. Thus, interfering high-frequency components are significantly reduced. At least two devices having different characteristics are preferably arranged on a vehicle.
