摘　　要：提出基于双推板的内孤立波数值造波方法,对两层流体中内孤立波与潜体的相互作用进行了数值模拟,分析不同潜深下潜体所受的内孤立波载荷特性。结果表明,内孤立波对水下潜体的载荷作用是不可忽视的。特别地,当潜体位于内孤立波中时,其所受的垂向力要远比潜体位于内孤立波下时的大。A method is presented for generating internal solitary waves based on the double-piston wave-making technology, the interaction between internal sohtary waves and a submerged body is numerically simulated, and the load characteristics of internal solitary waves on the submerged body are analyzed. Numerical results show that the internal solitary wave load on the submerged body can not be neglected. In particular, when the submerged body is located in the internal solitary wave, it will endure much more severely the interaction of the vertical force due to the internal selitary wave than the case in which the submerged body is located under the internal solitary wave.
