Towing cable mechanism 1 (41) pulls ship model (37) movement, reaches mark point (40) and stops pulling afterwards, makes ship model (37) in barrier (45)
Under the action of slowly stop.Meanwhile test data is transmitted to reality by the wireless radio transmission module of radio reception module (16)
It tests indoor Radio control module (22) and data processing system (23) carries out data processing, find out ship model in hydrostatic
The attitudes vibrations such as spacious water resistance, heave, trim.Testing crew is by assisting trailer (38) to shift ship model (37) onto after the completion of test
Test Preparation Area (46) carries out other three speed point (V2、V3、V4) resistance measurement.In each measurement process, ship model is opened
Stage beginning hawser tilt angle should keep identical, while cleaning water surface thin ice in time, keep the water surface without ice-like state, spacious after measurement
Water resistance is respectively as follows: ROW1、ROW2、ROW3And ROW4。
Ship model (37) is opened in test waters after water resistance is measured, and ship model (37) is moved on in laboratory (42) and is checked
The operating condition and extraction test data of various equipment.Meanwhile the water surface in waters to be tested being waited to freeze, test waters is freezing
The incipient stage needs the ice thickness of measurement in each hour in the process, the ice of measurement in every ten minutes when close to test requirements document thickness
Thickness, until icing thickness meets test requirements document.When ice thickness reaches test requirements document, it is sharp respectively in laboratory (42) to take out an ice cube
With microscope (28), scale instrument (29), low-reading thermometer (25) and densimeter (27) measurement ice ice in crystal structure, bubble and
The physical characteristics such as content, temperature, salinity and the density of brine bubble.Ice is subjected to slice using slicer (31) and is then placed in constant temperature
In case (32), carries out and be sent to other laboratories after Insulation and utilize three-head milling machine, lathe and three shaft multifunctional load testers
Carry out the mechanical characteristic measurement of ice.Ship model (37) is moved on to connection and debugging in flat ice navigation channel 1 (48) and tried by other testing crews
Equipment is tested, icebreaking resistance test is prepared under the conditions of carrying out flat ice for ship model (37).
