The effects exerted by the yaw motion of a single wheelset on its creep forces/creepages are investigated in the study.

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.

Study on prediction of FPSO pitch motion;

Natural circulation flow instability under rolling motion conditions was experimentally studied.

The effects of the system spatial distribution including mass distribution,rolling axes and double loops on natural circulation under rolling motion condition were studied theoretically based on the mathematical model of natural circulation flow with rolling motion.

Experimental results show that rolling motion may cause the coolant fluctuation which results in the periodical oscillation of wall and fluid temperatures.
