摘　　要：船舶在隧洞中采用一种曳引技术通航,为了探究曳引系统在通航过程中受到外部冲击力对船舶稳定性的影响,文章通过仿真分析与模型试验相结合的技术路线,以受到不同冲击力作用下船模姿态为依据进行分析。结果表明:曳引系统在不同牵引速度下,受到外部冲击载荷,均可保证船舶的稳定性,适当增加内部载荷能有效抵抗外部冲击力的影响。Ships employ a traction technology for navigation in tunnels.To explore how the external impact acting on the traction system influences ship stability during the navigation,this paper adopts a technical route combining simulation analysis and model tests for analysis depending on the attitude of a ship model.The results show that the traction system at different towing speeds can ensure the ship stability under an external impact load.In addition,an appropriate increase in the internal load can effectively resist the external impact.
