Abstract

The invention discloses an adjustable resonance block which comprises circular-cake-shaped bottom plate connecting pieces connected coaxially, a weight block and an elastic part. The bottom plate connecting pieces are in a circular cake shape. First bolts are arranged at the bottom face axes of the bottom plate connecting pieces. The first bolts are used for connecting of vehicle parts. The weight of the weight block can be adjusted. One face of the elastic part is connected with the top faces of the bottom plate connecting pieces. The other face of the elastic part is connected with the weight block. The adjustable resonance block is simple and regular in structure, accordingly, machining is easy, mounting and using are convenient, the bottom connecting pieces and the weight block are connected with circular faces through circular-cake-shaped rubber, the contacting area is large, connecting is stable and firm, the shape and the connecting mode of the elastic part are regular, and accordingly the rigidity of the resonance block can be easily controlled.

Description

technical field [0001] The invention relates to an adjustable resonance block, which belongs to the technical field of manufacturing automobiles and parts thereof. Background technique [0002] With the rapid development of the modern automobile industry, people have higher requirements for the comfort of automobiles. In the field of automobile manufacturing, NVH (Noise, Vibration, Harshness) is recognized as the main indicator to measure the comfort of automobiles. The resonant block involved in the present invention is a relatively passive technical means for improving the NVH of the whole vehicle in automobile research and development: that is, after the assembly of the whole vehicle is completed, it is tested for NVH. Resonance occurs at a frequency that causes deterioration of vehicle NVH, jitter and noise. A resonant block with the same frequency will be developed and assembled on this component to achieve the purpose of improving vehicle NVH. However, it usually take...
