Spend, and base II is fixed on a vibration table；
The U-like shape frame it is opening down, it has a base III and two sides, the U-like shape frame base III perpendicular to
The base I and the base III of the ladder frame are fixedly mounted on the base I of the ladder frame；
The threaded rod through U-like shape frame two sides and its be fixed on by nut on U-like shape frame, in addition, institute
Threaded rod is stated also at the opening of ladder frame through the ladder frame.
Preferably, the fixture also includes threaded sleeve, and the threaded sleeve is connected to institute by the internal thread of its inwall
State on the external screw thread of threaded rod, and the threaded sleeve is located between two sides of the U-like shape frame.
Preferably, the base II is bolted on shake table.
Preferably, the base III is mounted by means of bolts on the base I of the ladder frame.
In general, by the contemplated above technical scheme of the utility model compared with prior art, it can obtain down
Row beneficial effect：
1) the utility model clamp structure is simple, and assembly and disassembly are convenient, solve the vibrationproof in damper exciter test
Hammer can only upside-down mounting the problem of be unable to formal dress, make experiment safer, closer to actual conditions；
2) threaded rod and threaded sleeve are supported the use, and fixture is had preferably fixed imitate for the damper of various sizes
Really, the use scope of fixture is added, is conducive to carrying out the experiment of various sizes damper.
