摘要
基于切片法建立物体在静水中浮体上纵向运动时浮体的水动力特征及运动微分方程。物体对浮体的垂向作用力考虑为瞬时压力,采用4阶龙格库塔法求解浮体运动微分方程,并将计算值与试验数据进行比较。
Based on the strip theory, motion equations are established in time domain to describe the motions of the floating body at still water induced by moving load. The action between the moving mass and the floating body is described as instantaneous contact force. The solution of the motion equations is obtained by the 4th-order Runge-Kutta method, and the results are compared with experimental results.
