摘要: 静水阻力拖曳试验是评估水陆两栖无人车水动力性能的重要手段, 目前针对水陆两栖车航行阻力的静水拖曳试验流程及机理尚缺乏系统性研究。文中以某型水陆两栖无人车为试验对象, 基于其几何参数和设定的试验工况, 依托船模拖曳水池试验装置制定了规范化的试验步骤, 定量表征了不同拖曳速度和不同尾翼板安装角度下的流体动力性能。结合试验观测现象和数据集, 重点分析了航速与尾翼板安装角度变化对航行阻力特性、升沉运动响应及纵倾姿态的影响规律, 为水陆两栖无人车水动力性能优化提供了试验依据和工程参考。Abstract: The still water resistance towing test is an important method for evaluating the hydrodynamic performance of amphibious unmanned vehicles. Currently, there is a lack of systematic research on the still water towing test procedure and the underlying mechanisms of sailing resistance for amphibious vehicles. In this paper, a certain type of amphibious unmanned vehicle was taken as the test object. Based on its geometric parameters and the defined test conditions, a standardized test procedure was established using a ship model towing tank facility, and the hydrodynamic performance under different towing speeds and different stern flap installation angles was quantitatively characterized. Based on the observed experimental phenomena and the dataset, the effects of variations in speed and stern flap installation angle on sailing resistance characteristics, heave motion response, and trim attitude were analyzed in detail, providing experimental evidence and engineering reference for the hydrodynamic performance optimization of amphibious unmanned vehicles.
