Test content:
1) Resistance test (various conventional ship types and new concept ship types, including high-speed planing boats, hovercraft, hydrofoil boats, seaplanes, ground effect wing boats, underwater models, etc.);
2) Open water test (conventional propeller and ducted propeller, rudder propeller, pod propulsion and other combined propellers);
3) Streamline measurement (silk thread method, paint method); Three dimensional wake field testing; Measurement of ship waveform resistance, etc;
4) Wave test: wave test in top wave state and external load test;
5) Research on hydrodynamic testing of ocean engineering ship platforms, underwater towing bodies, and underwater robot foundations;
6) Calibration of precision speedometers, etc.
Test accuracy:
1) Practical operating speed range: 0.1m/s~22m/s; Can achieve bidirectional stepless speed regulation;
2) Speed accuracy: When the speed is below 1m/s, the speed test accuracy is relatively high
3) High and low speed division: Low speed division 6.0m/s; High speed gear>6.0m/s;
4) The forward acceleration during operation is greater than 0.07g:
5) Maximum braking deceleration: 0.2g;
6) Steady speed accuracy:
① When 0.1-1.0m/s, the absolute error is ± 1mm/s;
② When the speed is between 1.0 and 22.0m/s, the relative error should not exceed 0.1%;
7) Maximum braking deceleration: 0.2g;
8) Adopting four-wheel drive and four-wheel DC motor drive mode.
