Test Platform of Anti-rolling Tank and Experimentation Research on Motion of Rolling and Swaying;

Simulation and characteristics analysis of the coupling motion of maneuvering and rolling for a ship in regular waves

High-efficient flap type rudders with 45°dip angle are installed in order to control the course, rolling and pitching simultaneously.

A study of the roll motion model of a flooded ship in waves;

Study of roll performance and reduction of boxshaped ship with extrashallow draft;

Research on ship course/roll robust control

The coefficients and the first order rolling moment in the first order rolling motion equation and the rolling response function per unit wave front angle are obtained.

The rolling motion of an unstabilized ship and a stabilized ship equipped with fin stabilizers has been predicted by use of a random wave model.

According to the condition as mentioned above,a typical linear roll motion equation was set up, and the expressions of natural angular frequency and nondimension damping decay modulus of amphibious combat weapon were given.

It is well know that roll motion of amphibious combat weapon in regular wave will severely affect the battle effectiveness of crew in the amphibious combat weapon and the fire accuracy.

The method used to simulate ship roll motion by the equipment was analyzed.

Analysis of ship parametric rolling in head sea;

A numerical simulation method based on ITTC recommendation was used to investigate the occurrence and magnitude of parametric rolling in longitudinal regular waves.

Parametric rolling is a kind of the resonance phenomena of ship motions, caused by the periodical fluctuations of stability parameters of ships in waves.
