新概念穿梭艇自航模操控系统试验研究

摘要

The free-running model test is an effective way to evaluate ship performance. In this paper, a Manipulation and Control (MC) system is designed for a new concept shuttle vessel. The MC system in⁃cludes two parts:an ashore control system and an onboard control system, and the two parts exchange infor⁃mation through a Wireless Local Area Network (WLAN). The actuators of the shuttle vessel are equipped with sensors to obtain the feedback data, and certain sophisticated programmable elements are incorporated as the drivers of the actuators, where the lower and upper computer software are both written in the Python programming language. The MC system is then successfully applied to the free-running model test of the new concept shuttle vessel. Experimental results indicate that the MC system is efficient in terms of the de⁃velopment effort, easy to be operated, and has good scalability and portability. The maneuverability of the new concept shuttle vessel is well demonstrated through the free-running model test results. Finally, the free-running experiment results tested with the MC system is compared with the actual towing tank data, which shows high consistency.%自航模试验是研究船舶性能的有效手段。针对新概念穿梭艇，设计一种自航模操控系统。该系统包括岸上操控系统和船载自航控制系统2部分，利用无线局域网完成岸上操控系统与船载自航控制系统之间的通信；执行机构配备传感器获取反馈数据，驱动器采用成熟的可编程元件；使用Python语言编写下位机和上位机软件。将系统成功应用于新概念穿梭艇的自航模试验中，试验表明所设计的自航模操控系统可以减小开发工作量，操作方便，可扩展性和可移植性强，能够反映新概念穿梭艇的操纵性能。最后经与船模拖曳水池试验结果进行对比，证明所设计系统应用于自航模试验时能够有效获取可靠数据。
