| 摘要 |
The invention relates to a vibrating plate (1), with a baseplate (2), set in vibration by means of a driving device (9), with at least one bottom plate (3), an upper plate (4) and a cell structure (5), arranged between the botto m plate (3) and the upper plate (4) to reinforce the base plate (2), as suppor t components. According to the invention, the support components form a baseplate (2) with a natural resonance frequency 2 to 5 times, preferably 3 to 4 times the frequency of the vibration thereof. The support components (3, 4 , 5, 8) are thus welded together to form a self-supporting body, such as to gi ve a particularly stiff and light baseplate (2). As a result of the above properties, said vibrating plate (1) is particularly suitable for compacting uniform sands and snow, for example in the preparation of ski pistes.</SDOAB >
