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.

Time series prediction of ship rolling;

The experiments of ship rolling time series prediction are done using the error back propagation neural network, the results performed well.

Time series prediction of ship rolling based on two direction difference;

Long-term prediction of ship roll motion based on hybrid model of WT and MGFPE;

The stationary probability density function (PDF) and the stationary mean out-crossing rate (MOR) of the response of ship nonlinear roll-motion subjected to additive stochastic white noise excitation are examined by a new approximate method in this paper.
