Five times.
6. a kind of test method using any marine environment simulation test device of claim 1-5, comprising the following steps:
Water inlet step S1, electronic control unit (400) control supply line (202) water inlet and real-time monitoring liquid into experimental cabin (100)
The feedback liquid level of level sensor stops water inlet when feeding back liquid level and reaching test requirements document；
The step S2 continuously to boost: electronic control unit (400) controls gas-liquid booster pump (210) air inlet and water inlet simultaneously, and by gas
It injects in liquid after compression, is continuously inputted the liquid with compressed gas by water inlet pipe (122) by pressure pipeline (201)
In to experimental cabin (100)；
The step S3 being continuously depressured: from drainpipe (121), continuously discharge is tested for electronic control unit (400) control decompression pipeline (204)
Micro liquid in cabin (100)；
The step S4 of continuous warming: electronic control unit (400) controls four-way reversing valve (303) for the compressed gas of compressor (301)
It accesses temperature control pipeline (132)；
The step S5 of continuous cooling: electronic control unit (400) controls four-way reversing valve (303) for the compressed gas of compressor (301)
It is linked into that gas-liquid separator (304) gasify and heat exchanging device (302) is cooling；Electronic control unit (400) controls four-way reversing valve
(303) cooling gas of heat exchanger (302) is inputted into temperature control pipeline (132)；
Simulate step S6: electronic control unit (400) control spiral propeller assembly (140) operating of masses hit, the spiral
Propeller assembly (140) generates high speed water jet impact trial target；
Drain step S7, electronic control unit (400) control discharge pipe line (203) and the liquid in experimental cabin (100) are discharged；
The step S2 to step S6 is carried out according to test requirements document synchronization or individually, regardless of order.
