Embodiment Construction

[0017] The present invention includes elastomeric materials inserted into gap-filling materials such as figure 1 and figure 2 as shown. Item 101 represents elastic material, such as webbing in a mesh structure. Item 102 represents a gap fill material. Item 101 is inserted into item 102 to form an overall structure of coupled damping layers (item 100). The webbing web forms the primary structure of the thin layer so as to limit the compression of the attached gap filling material to a limited thickness. On the other hand, gap-filling materials serve the main functions of vibration coupling and dynamic behavior of the entire structure. The elastic nature of the inserted elastomeric material allows the transmission of shear and compressive forces in all directions. Inheriting the physical properties of gap-fill materials, the design is also capable of directing shear flow.

Abstract

The invention is a coupling-damping thin layer of gap-filling material to be used at interfaces under compression and the thickness control techniques. By insertion of the layer between the vibrating surface and vibration control device, the working efficiency of vibration coupling layer and hence of the vibration control could be maintained over a prolonged period of time. Apart from the application as a vibration coupling layer stated above, the invention can also act as a damping layer to modify the overall dynamic properties.

Description

technical field [0001] The present invention relates to a thin layer of solid gap-filling material for coupling on a vibrating object, which enhances the coupling of small amplitude (<1 μm) vibrations and provides hysteresis loop damping for strong vibrations, and when the vibration force is greater than the gap-filling Techniques for controlling the thickness, viscoelasticity, and viscoplasticity of a material at its plastic flow yield value. Background technique [0002] Gap filling materials such as beeswax are widely used to fix the vibration sensor to the measurement surface to ensure that the vibration is transmitted to the sensor. For this reason, it is necessary to control the thickness of the gap-fill layer. In addition, typical gap filling materials such as beeswax, etc. will tend to creep or flow out from the contact interface when under compressive force during one or more oscillation cycles. This can lead to a loose fit and can interfere with the vibration ...
