Embodiment Construction

[0014] Example embodiments include a shielding plate 2 in the motor area of ​​the vehicle, such as figure 1 shown. The corrugations, indentations and protrusions 4 of the shielding plate are drawn, for example, by dot-dash lines; depending on the component, such indentations 4 can also be completely absent or configured differently. At the edge of the shielding plate, likewise by way of example, through-holes 6 and fastening regions 8 are shown, by means of which the shielding plate 2 can be screwed or riveted to the component, for example.

[0015] The expected vibrations of the shielding plate 2 during operation can now be determined from measurements on the installed components or predicted on the basis of calculations and / or simulations. Thus, for example, the natural resonance frequency and higher vibration modes of the shielding plate can be determined. In this way, it can be established which frequencies will occur and which areas of the shielding plate will be partic...

Abstract

The invention relates to a vibration elimination system, comprising a shielding plate (2) for a motor component, at least one vibration elimination element (10) that is fastened to the shielding plate (2), wherein each vibration damping element (10) comprises a spring-mass system that is capable of vibration, the spring force and mass of which are dimensioned such that said spring-mass system is matched to a predetermined vibration frequency of the shielding plate (2).

Description

technical field [0001] The invention relates to vibration dampers, in particular vibration dampers for shielding plates on motor components. Background technique [0002] Motor vibrations and airborne sound generated by motor components stimulate natural vibrations in vehicle components such as heat shields. These vibrations can lead to undesired acoustic and stability-related damage on the shielding plate. [0003] Heretofore, component vibrations have been taken into account when providing reinforcement measures, for example by introducing ribs or corrugations into the geometry of the plate, eg on shielding plates and similar components. However, it is often difficult to create an optimal corrugation distribution on the plate for reinforcement purposes, for manufacturing reasons or at locations with narrow installation spaces. [0004] A further measure for reducing vibrations of the components is to use vibration decoupling elements which are mounted between the compone...
