Description
Technical field：The invention belongs to aircraft ground experiment field, it is related to a kind of fuel tank to rock and vibrational system and its method.
Background technology：Fuel tank shakes the 965th article of checking test of requirement that experiment of shaking is the seaworthiness such as CCAR, FAR 23 and 25.Fuel tank shakes
Pilot system of shaking shakes experiment of shaking for carrying out fuel tank.Fuel tank shakes pilot system of shaking, and mainly the frock clamp including constrained test part, vibratory drive set
It is standby, rock driving equipment, rock Angle Measuring Equipment, vibration amplitude measuring apparatus and time-measurement device.Frock clamp, vibratory drive equipment,
Driving equipment is rocked for chief component.Wherein, frock clamp is used for constrained test part, transmission vibration, and vibratory drive equipment and rocks driving
Equipment drives testpieces to vibrate and rocked around axle respectively.
At present, domestic fuel tank shakes experiment of shaking and is required for being carried out on the shake table in laboratory, and frock clamp is required for being installed on shake table.And
Large vibration table is difficult to be transported to aircraft manufacturing factory from laboratory, Domestic Aircraft manufacturer be required for when fuel tank shakes and shakes experiment by testpieces from
Factory is transported to specific laboratory, expends a large amount of manpower and materials.Frock clamp is installed on shake table, increased the difficulty of fixture installation.In order to
Realize near-earth being carried out in aircraft manufacturing factory to the fuel tank development experiment for testing, meeting different sizes and shapes, the present invention provides a kind of novel fuel
Case shakes pilot system of shaking.It is the system simple structure, easy to use, fuel tank can be completed and rocked experiment with Vibration Synchronization, and easy to disassemble,
Storage, transport, can effectively reduce the cost that fuel tank shakes experiment of shaking.
The content of the invention：In order to solve the above-mentioned technical problem, the present invention shakes pilot system of shaking and is improved to fuel tank, and proposition is rocked driver element, shakes
The new rolling that dynamic driver element and constrained system are integrated in one is shaken pilot system.Driver element, vibratory drive unit are rocked respectively by simple connection
Unit such as connecting rod, contiguous block etc. are integrated into one and shake pilot system of shaking with the frock clamp of constrained test part.Shake table is driven into frock clamp and experiment
The traditional approach of part vibration is changed to motor, the mode of the simple unit direct drive testpieces vibration of connecting rod composition.The installation foundation of frock clamp is by shaking
Dynamic platform is changed to ground, is easy to frock clamp to be installed on aircraft manufacturing industrial building ground or track.Novel tooling can meet different length chis
Very little and containing bending-type spar wing fuel tank carries out the demand for shaking experiment of shaking, and satisfaction rocks angular measurement demand, and frock is readily disassembled, stores and transports
It is defeated, can implement to test in aircraft manufacturing factory site.
The technical solution adopted for the present invention to solve the technical problems is：
Step one：Design is a set of to place or is fixed on ground or the frock clamp of track, meets different length sizes and containing bending beam
The demand of wing fuel tank testpieces fixed installation, meets the demand of vibration and pivoting, and satisfaction rocks angular measurement demand；
Step 2：Rock bent axle of the motor by being connected with the testpieces mounting rail on frock clamp and drive testpieces around the rotating shaft of frock clamp
Rock；
Step 3：Motor is converted to shaking for frock clamp tie point by vibratory drive motor by rotary shaft, vibration converting unit and connecting rod
It is dynamic, and then it is converted into the vibration at testpieces rotating shaft.
Beneficial effects of the present invention：Novel fuel tank shakes pilot system of shaking, and frock clamp is associated with vibrational system by connecting rod or contiguous block, it is to avoid
Come mounting tool fixture and testpieces using large vibration table, while fuel tank again can be met rocks the requirement that excitation and vibrational excitation apply simultaneously.
It is small that Novel fuel tank shakes shake pilot system simple structure, size, it is easy to installing/dismounting, storage and transport so that fuel tank shakes experiment of shaking can fly
Machine manufacturing works carry out, and save time and the fund cost of research ＆ development in flight.
Brief description of the drawings：
