The sensor acquisition method of environment composite test is different, and the former is to use non-contact sensor collection, Hou Zheshi
Employing touch sensor gathers, as directly used mechanical environment and climatic environment composite test method to carry out
, can there are two big problems in the testing fatigue of blade of aviation engine, one is blade of aviation engine testing fatigue
Temperature higher, generally to reach 700 °～900 °, and mechanical environment and climatic environment composite test is the highest
Temperature is 200 °, and gathering sensor can not at high temperature work, the problem causing signals collecting；Two is vibration
Platform and climate box connectivity problem, owing to being at high temperature to work, the joint portion of vibration table and climate box cannot
Installing traditional soft attemperator additional, the sealing of climate box is a problem.Therefore develop a set of energy and be suitable for boat
The device that empty engine blade carries out composite fatigue test is the most necessary.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide one can make sensor at high temperature
Carry out signals collecting, can blade be carried out tired under true environment (i.e. mechanics and the combinational environment of weather) again
The device of labor test.
The test device of engine vane fatigue degree of the present utility model, including having shaking of extensional vibration table top
Dynamic device, described vibration table connects high-temperature cabinet, is provided with and is connected with described vibration table in described high-temperature cabinet

Further, described vibrating device is electric vibration table.
By such scheme, this utility model at least has the advantage that
1, longitudinal vibration table is utilized so that blade can be with in the vertical direction oscillation crosswise, and by high temperature
Case is arranged on the side of vibration table so that heat high-temperature cabinet upwards may insure that the temperature around blade is equal
Even unanimously reach required analog temperature, it is ensured that test result is consistent with true environment, and traditional survey
Electricity testing device cannot ensure that the homogeneous temperature around blade is consistent；
2, owing to high-temperature cabinet being arranged on the side of vibration table, heat flows upward through blade, thus
Sensor can be made to carry out signals collecting from side to blade, and the high-temperature heat flux flowed up will not be to the biography of side
Sensor impacts so that sensor at high temperature can not carry out signals collecting by temperature influence, and traditional
High-temperature cabinet is arranged on the mode above vibration table, and the heat flowed up in high-temperature cabinet can affect and be arranged on
Sensor above high-temperature cabinet so that sensor can not at high temperature work, solves traditional test device
The technical problem existed；
3, under the combinational environment of vibration and high temperature, by graphite annulus, vibration table is sealed with high-temperature cabinet, close
While envelope, graphite annulus can provide again the amplitude space that support vibrates with vibration table, solves under high temperature high
Incubator and the sealing problem of vibration table.
Described above is only the general introduction of technical solutions of the utility model, in order to it is new to better understand this practicality
The technological means of type, and can be practiced according to the content of description, below with preferable reality of the present utility model
After executing example and coordinating accompanying drawing to describe in detail such as.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation that in this utility model, high-temperature cabinet is connected with support.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.
