Abstract

The invention belongs to the field of measuring equipment and particularly relates to a damping characteristic measuring device. The damping characteristic measuring device includes a first fixing part, at least two bearing parts, at least connecting parts, a fixing assembly, an elastic vibration part, a counterweight part and a clamping assembly, wherein the at least two bearing parts are mounted on the first fixing part; the connecting parts and the bearing parts are arranged in a one-to-one correspondence mode, and the connecting parts are movably installed on the bearing parts in the extending directions of the bearing parts; the fixing assembly is used for fixing the connecting part to a preset position of the bearing part; the elastic vibration part is fixed between the at least two connecting parts in a suspended manner; the counterweight part is arranged in the middle of the elastic vibration part; the clamping assembly comprises a first clamping part and a second clamping part, the first clamping part is connected with the elastic vibration part, the second clamping part is connected with the first fixing part, and meanwhile, the first clamping part and the second clamping part are connected through the damping material to be tested. The device is advantaged in that the effect of expanding the application range of the measuring device is achieved.

Description

technical field [0001] The present application belongs to the field of measuring equipment, and more specifically relates to a damping characteristic measuring device. Background technique [0002] As we all know, the damping characteristics of viscoelastic materials have a non-negligible position in the field of vibration reduction and vibration isolation. If the most suitable damping material is found in actual engineering, the vibration isolation effect can be greatly improved and more benefits can be generated. Therefore, accurate measurement It is particularly important to obtain the damping coefficient and vibration isolation effect of the damping material. [0003] Most of the existing devices for measuring the damping of viscoelastic materials have certain limitations in application. Not only do they have high requirements for the operation of the experiment, but the range of testing damping sheets is limited, especially for smaller damping sheets. Contents of the ...
