The standard suboff model is designed by steel structure and covered with FRP material. Aiming at different sword types and connection modes of swords and suboff model, the resistance experimentation is conducted under shallow water condition, The experimental results of different sword types and connection modes compared to the ITTC results are analyzed, then based on the CFD method, by observing the distribution of velocity and pressure under different velocity values, the influence of connective sword on the flow field is analyzed.%采用钢骨架外敷玻璃钢的结构加工设计Suboff标模，针对不同的剑型以及剑艇连接方式，采用浅浸深方式开展艇模水下阻力试验，分析不同剑型与连接方式所带来的结果差异，并将其结果与ITTC公布的试验数据进行对比，最后在数值仿真的基础上，通过观察不同速度下的流场流速以及压力分布情况，分析连接剑装置对艇流场的影响。
