针对水面无人船适应复杂海况航行的需求，提出一种适用于三体船的柔性连接桥原理构型。通过构建粘流数值波浪水池并结合重叠网格技术，实现了具有主体和侧体共六自由度的相对运动的流体动力学仿真。仿真结果初步表明，采用柔性连接桥后能够有效改善三体船在波浪中航行的阻力性能，且在一定波长范围内可以改善垂荡性能。
Aiming at improving the seakeeping performance of unmanned surface vessels, a flexible connection prototype suitable for trimaran is proposed. By applying viscous flow numerical wave pool combined with overlapping grid technology, computational fluid dynamics simulation on 6-dof relative motion of the main body and side body is realized. The simulation results show that the flexible connection prototype can effectively improve the resistance performance of the trimaran in the wave, and can improve the heave performance in a certain wavelength range.
