Abstract

The extreme motion area, draft depth, steel pipe The extreme motion area, draft depth, steel pipe tilt angle and other parameters of the buoy are solved step-by-step with taking more parameters into account: single parameter of wind speed, double parameters of wind speed and heavy ball quality, multi parameters of wind speed, heavy ball quality, wave impact force and sea water depth. Firstly, the stress of the joint is decomposed. Then combining the solving condition that the vertical height between the anchor and the sea surface is equal to the water depth, according to the dichotomy, we can approximately get the inclination angle of steel pipe and steel drum and the swimming area and draft depth of the buoy under the situations that the angle between the bottom of the chain and the horizontal line is less than 16 degrees, the angle between the steel drum and the vertical line is less than 5 degrees, the wind speed is 12m/s, 14m/s, 36m/s. With the increase in wind speed, we found that the angle between the steel drum and the vertical line does not meet the conditions, and we need to increase the quality of steel balls and change the anchor chain model to adjust the tilt angle of steel drum. Finally, in the case of high wind speed, the ball quality should be at least 1928.07kg or at most 4531.64kg
