摘　　要：通过对潜体近水面航行波浪力作用下非线性运动响应进行建模和计算，揭示了由于二阶波浪力作用与低速时潜艇操纵面舵力之不足，潜体的定深控制可能难于实现，产生逐渐上浮与露出波面的非线性现象。计算结果与自由自航模的试验结果相当吻合。According to the modeling and predicting of nonlinear motion responses of a submerged slender body running near water-surface due to the wave-exciting forces, it is found that the mean drift wave forces can make the submerged bogy tend to move upwards. In serious status, it may emerge from water if the control forces of maneuver system(rudders) cannot offset the mean drift forces. Calculational results are good with that obtained from the self-propelled model test in oblique sea in the seakeeping basin of CSSRC.
