Description
Technical field
The invention belongs to engineering hydrodynamic test fields, and in particular to a kind of submarine navigation device model stability test mould
Block.
Background technology
Submarine navigation device, need to be reduced than making corresponding model in Special test according to one before carrying out formal engineering development
Hydrodynamic(al) experiment is carried out in pond, underwater stability test is a wherein important content of the test, tests main test mould
Posture (angle) when type moves under water on solid axes x, y, z direction and load (acceleration) variation.
Conventional method be angle, acceleration transducer and harness part are designed together together with model, and fasten together,
Weight proportion, encapsulation process.It does so and experimental test requirement may be implemented, but increase test model complexity, increase
Mould processing difficulty.High-precision sensor changes bad border more sensitive simultaneously, and submarine temperatures variation is violent, seriously affects biography
Sensor measuring accuracy；Watertightness requirement when being navigated by water under water for model is also very high, and entire model Anywhere occurs one
The danger of dot encapsulation problem, sensor or even entire test systems face damage.In addition, underwater campaign test mode compared with
It is more, it can accordingly increase required test model, carrying out testing required test sensor will also increase, and improve experimentation cost, and
And the difference between sensor individuals is also unfavorable for the required precision of test.Therefore underwater sailing body stability examination is being carried out at this stage
In the presence of such as modelling difficulty is big, seal request is high, experimentation cost is high, test equipment poor universality, precision can not protect when testing
The series of problems such as card, it is difficult to meet Practical Project experiment demand.
Invention content
The purpose of the present invention is：A kind of data accuracy, reliability and watertightness are provided and disclosure satisfy that design requirement, simultaneously
The high submarine navigation device model stability test module of measuring accuracy.
The technical scheme is that：A kind of submarine navigation device model stability test module comprising, shell 1, sensing
Device 2, waterproof plug 3, outer casing base 4, closure head 5, electronic temperature controller 6, wherein the setting of the closure head 5 exists
1 top of shell, the two are engaged by catching groove and are sealed, and the setting of outer casing base 4 is arranged in 1 bottom of shell, sensor 2 in shell 1
Below portion, connect electronic temperature controller 6, waterproof plug 3 is arranged above closure head, sensor 2 and waterproof plug 3 it
Between connected by lead, and waterproof plug 3 is also associated with external lead wire, and the sensor 2 is integrated acquisition x, y, z orientation angle
With the inertial gyroscope of acceleration change.
The sensor is integrated with electronic temperature controller.
There are sealing ring in closure head top and bottom.
It is coated with grease above the sealing ring.

Watertightness, 6, be electronic temperature controller, keep sensor where interior environment temperature it is constant, ensure sensor test essence
Degree.
Specific implementation mode
The present invention will be further described with reference to the accompanying drawings and examples：
Please refer to Fig. 1, Fig. 2 and Fig. 3, submarine navigation device model stability test module of the present invention includes shell 1, passes
Sensor 2, waterproof plug 3, outer casing base 4, closure head 5, electronic temperature controller 6.Wherein, shell uses stainless steel
Matter, guarantee do not deform under water.The closure head 5 is arranged above shell 1, and the two is engaged by catching groove and is sealed, together
When closure head top and bottom have sealing ring, be coated with grease above sealing ring, can effectively ensure that leakproofness.The outer casing base 4 is set
It sets in 1 bottom of shell.The setting of the sensor 2 is in 1 lower inside of shell, for integrated acquisition x, y, z orientation angle and acceleration
The inertial gyroscope of variation ensures that accurately required data are tested in acquisition in the environment of high frequency sound, while being connected with electronic type temperature
Controller 6 is spent, and the angle of sensor, acceleration transducer become one with electronic temperature controller 6, ensures module
Interior environment temperature is constant, avoids due to sensor zero drift caused by the variation of high temperature under water, improves sensing
Device measuring accuracy.Waterproof plug 3 is arranged above closure head, and using the aviation waterproof adapter of high standard, protection level reaches
To IP68 ranks.It is connected by lead between sensor 2 and waterproof plug 3, and to be also associated with external lead wire another for waterproof plug 3
Outside, wiring harness junction is pulled and pushed using belt lock catch, ensures harness connective stability.
In submarine navigation device model stability test module underwater sailing body stability test of the present invention, process mould is tested
Design requirement is fully achieved in block normal operation, data accuracy, reliability and watertightness etc., and measuring accuracy reaches within 1%, reaches
Test requirements document is arrived.
