Abstract
To conduct ship model inclining experiments and floating state adjustment experiments, a static experiment system is developed, including research and development of hydrostatic flume, connecting frame, attitude instrument and data acquisition and analysis processing module. And the work principle of the system is discussed. Furthermore, ship model inclining experiment, floating state adjusting experiment, and roll, pitch, heave free decay experiment are conducted to analyse the performance of this system. Results of the experimental indicate that the system has a satisfactory testing precision. In the model inclining experiments, relative error of vertical coordinate of center of gravity of the ship model is 1.5%, relative error of the longitudinal coordinate is 0.18%; in the floating state adjusting experiment, standard error of transverse inclination is 0.06 degree, standard error of longitudinal inclination is 0.03 degree, standard error of heaving measurement is 0.15mm; the free decay experiment proofs that the experiment system can realize dynamic measurement of roll, pitch and heave. This experimental system with high precision has a good application prospect which can be used in ship model inclining experiment, floating state adjusting experiments, as well as model hydraulic performance test study.
