Experimental Research on Near-water-surface Skipping Motion of Vehicle

摘要:

航行体近水面滑跳运动是近年来跨介质航行体研究的热点问题之一,针对航行体水面滑跳运动现象开展研究。 首先设计了适宜滑跳的航行体构型,通过数值仿真方法确定航行体的主要技术参数,发现航行体滑跳过程对于重心位置非常敏感;然后,针对设计的构型,开展水面自由滑跳试验,试验表明本文设计的模型可以在近水面稳定滑跳,验证了滑跳运动方式的可行性。 工作可为后续跨介质航行体设计提供技术参考。

Abstract:

The near-water-surface skipping motion of a vehicle is one of hot topics in the field of trans-media vehicle research in recent years. This paper focuses on the phenomenon of the skipping motion of a vehicle on the water surface. A vehicle configuration with the ability of skipping is designed and the main technical parameters are determined based on numerical simulations. It is found that the skipping process is very sensitive to the position of mass center. Then, free skipping experiments are carried out aiming at the designed structure. The results show that the model can skip near the water surface stably, which verifies the feasibility of the skipping motion. The study in this paper can provide references for the design of the trans-media vehicle in the future.
