Test Platform Of Anti-rolling Tank And Experimentation Research On Motion Of Rolling And Swaying

The anti-rolling tank is one of stabilizing equipments, and it fits for ships working at zero speed or low speed such as passenger and train ferry, roll-off vessel, research and exploration vessel and so on in particular. In order to provide data reference for ships equipped with anti-rolling tank, based on the item the Anti-rolling Tank Test Equipments on the Ship among the country 211 key construction projects, the paper goes on deep analysis and research on test platform of tank and motion of rolling and swaying.First, mathematical model of swaying system is made, which is a basis on later chapters. Meanwhile, the system is simulated and designed. The effect of loaded mass, loaded suppleness, general leaking coefficient and cubage elasticity modulus on performance of system is also analyzed. According to the model, some kinds of parts of an apparatus are choosed and stability, error, time-domain and frequency-domain are presented.Afterwards, in order to analog more ships, the characters of tank's mechanical parts are given. At the same time, effects of variation of bob-weight mass and distance of slip pieces are researched. From the whole system, analysis of input signal, oil-source, electro-hydraulic servo valve, controllers, amplified circuits and so on is provided.In addition, from theoretical background, rolling motion with swaying is simulated.Finally, plans are made, experiments are finished and phenomena and data are discussed. During the debugging and experimentation, some taches and questions needed attention are summed up, which sets up the basis on later research. What's more, some further research and suggestions are provided.
