| Abstract: | The air duct and the valve port of passive controlled anti-rolling tank will generate damping effect on the oscillation of water in the tank and lead a negative impact on rolling reduction.This paper analyzes the oscillation characteristics of the water in the tank under the effect which is generated by the air duct(including the valve port).And the paper puts forward the method of calculation about additional damping coefficient caused by air duct and the method of calculation about rolling reduction under... |
