Vibration isolation assembly based on high-frequency high-damping vibration isolation disc-shaped gasket

Abstract

The invention discloses a vibration isolation assembly based on a high-frequency high-damping vibration isolation disc-shaped gasket. The vibration isolation assembly comprises a bolt and a nut, and further comprises two damping alloy discs, a flat gasket, an upper simulation assembly and a lower simulation assembly which are arranged on the bolt in a sleeving mode, the two damping alloy discs areinstalled between the upper simulation assembly and the lower simulation assembly, the flat gasket is installed between the two damping alloy discs, the nut is screwed on the bolt from the outermostside, each damping alloy disc comprises an inner edge and an outer edge, the inner edges protrude in the axial direction relative to the outer edges, so that the whole damping alloy discs are in a circular truncated cone shape, a plurality of tooth protrusions are arranged on the inner edges in the circumferential direction, and the tooth protrusions of the two damping alloy discs are symmetrically arranged. According to the vibration isolation assembly, a transmission vibration isolation structure can be replaced, non-specific external high-frequency vibration is restrained and isolated, thecost is reduced, the space occupation requirement is reduced, the light weight degree of a vehicle is improved, and the control comfort is improved.

Description

Technical field [0001] The invention relates to a vibration isolation assembly, in particular to a vibration isolation assembly based on a high-frequency and high-damping vibration isolation dish-shaped gasket. Background technique [0002] In mechanical equipment systems, due to the presence of external or internal power sources, the system will produce varying degrees of vibration, and this type of vibration will mostly affect the operation of the equipment. In order to reduce the impact of vibration on equipment, many damping measures have appeared, such as using special damping equipment such as springs, active / passive dampers to dampen or isolate vibrations. However, each vibration reduction method can only isolate the corresponding vibration isolation frequency. In addition, most of these vibration reduction equipment have complex structures, large space occupations, and high costs. They are usually used in applications where the spatial structure size is not high and the c...

Problems solved by technology

For such high-frequency components with non-specific frequencies, the current mainstream method is to use rubber pads with large structural dimensions or hydraulic dampers to achieve vibration suppression. This method not only takes up a lot of space, but is also expensive
