Displacement is loaded.These aspects cause the performance difficulty of Ground Vibration Test larger.
The requirement of spatial pipeline system vibration test is a lot, it is necessary first to meet the filling of the medium such as air-liquid in pipeline；Need simultaneously
Meet the angle installation that spatial pipeline system is complicated and can not predict；Then the loading of three axial displacements of satisfaction is needed；It is last
It is the transmission that vibrational energy is met the need for most critical.Therefore, a kind of spatial pipeline system vibration test fixture of active demand can expire
Sufficient these requirements, realize being smoothed out for carrier rocket pipe-line system vibration test, complete the ground certification test of carrier rocket.
The content of the invention
Present invention solves the technical problem that being：For the experiment of the device space such as current carrier rocket pipeline vibration, probe tube
Road connection angle can not be predicted in advance, while pipeline vibration experiment needs to carry out the demands such as displacement loading, devise a kind of space
Pipeline vibration test fixture, is required except meeting spatial pipeline system connection request, vibration test displacement loading；Meet simultaneously in pipeline
The requirement of the coated by dielectric such as gas-liquid, the delivery request of vibrational energy.
This practicality type is disclosed：A kind of spatial pipeline system vibration test fixture, including support meanss, vertical means, rotation
Device, attachment means and adjusting means；Wherein described support meanss thickness is 30mm, is consolidated by adjusting means and vibration table surface
Fixed connection；It is 90mm to have three length in the support meanss, and width is 13mm translot, and the vertical means thickness is
30mm, it is 200mm above to have three length, and width is 13mm vertical slot, and the two is connected using adjusting means；On the vertical means
There is a diameter of 60mm, width is 13mm two 120 ° of circular grooves, and the rotating device thickness 30mm above there are two apart from 60mm
Individual diameter 13mm through hole, the two is connected by adjusting means；There are diameter 50mm through holes on the rotating device, for through institute
State attachment means；Described attachment means one end is flange-interface, and the other end is pipeline hickey, and attachment means are by spatial pipeline system
Fix and support with the spatial pipeline system vibration test fixture, hickey is directly connected with experiment pipeline, flange-interface and gas-liquid
Medium filing provision is connected.
Further, the making material of the spatial pipeline system vibration test fixture is exotic material steel.
Further, the spatial pipeline system vibration test fixture uses integral processing, is cut out using exotic material steel
Go out fixture.
Further, described adjusting means at least 8, adjusting means can be screw and screw rod.
Beneficial effects of the present invention：
(1) present invention solves spatial pipeline system vibration test angular adjustment, displacement loading, gas-liquid filling, vibration transmission etc.
Technical problem；
(2) secondly the present invention uses overall processing, and the installation that can be done without the sampler space pipeline of precise angle will
Ask, three direction displacement loadings of pipeline require that inside gas-liquid filling is required when pipeline vibration is tested, and vibration examination before vibration test
Effective delivery request of vibrational energy when testing.
