摘　　要：为揭示圆碟形水下滑翔机在近自由面作业时受波浪影响下的运动响应特性,利用粘流CFD技术开展近自由面圆碟形水下滑翔机水动力数值模拟。首先,对圆碟形水下滑翔机在大攻角条件下的水动力性能进行计算;其次,研究圆碟形水下滑翔机在不同来浪条件和距自由面距离下的水动力性能及其动态运动响应。研究结果表明,随着航速的增加,圆碟形水下滑翔机的升力、阻力和俯仰力矩的绝对极值均增大;波高和波长的增加会使圆碟形水下滑翔机的下潜距离增加,同时减小俯仰角并降低滑翔速度。随着圆碟形水下滑翔机距自由面的距离增加,波浪对其运动响应的作用逐渐减弱,圆碟形水下滑翔机的运动趋于稳定。In order to explores the motion response characteristics of a disc-shaped underwater glider operating near the free surface under the influence of waves,using viscous flow CFD technology for numerical simulations.The analysis first evaluates the glider's hydrodynamic performance at large angles of attack and then examines the effects of varying wave conditions and distances from the free surface on its dynamic motion response.The results indicate that as the glider's speed increases,the extreme values of lift,drag,and pitching moment also rise.Additionally,higher wave heights and longer wavelengths lead to greater dive distances,reduced pitching angles,and slower gliding speeds.As the glider moves farther from the free surface,the impact of waves on its motion response decreases,resulting in more stable behavior.
