圆柱浮体的平衡姿态及其稳定性

STUDY ON THE EQUILIBRIUM ATTITUDE AND STABILITY OF BUOYANT CYLINDERS

  • 摘要: 浮心相当于浮体的支承点,其位置随物体的姿态而变化;物体稳定平衡时重心与浮心的距离达到极小。圆柱浮体有2~5个平衡位置,其中相间的1~2个稳定,其姿态与比重和长径比相关,在系统参数变化时可能突变。

     

    Abstract: A floating object is just supported at the buoyant center, which varies with the equilibrium attitude of the object. It is stability at the least distance between the gravity center and the buoyant center. A floating cylinder may have two to five equilibrium positions, of those one or two are stable. The stable posture is related to its specific gravity and the ratio of length to diameter, and catastrophe maybe induced as the system parameters change continually.
