摘 要
船模拖曳系统的幕布悬挂系统是一种关键设备,它主要用于船模拖曳试验中,为船模提供必要的支撑和保护,同时满足特定的试验需求。以下是关于船模拖曳系统。幕布悬挂系统的主要功能是支撑和保护船模,同时为船模提供必要的稳定性和操作便捷性。在船模拖曳试验中,幕布悬挂系统需要能够承受船模的重量,提供足够的支撑力,保证船模在水面上的稳定性和安全性。此外,幕布悬挂系统还需要具备易于安装和撤收的特点,以便在试验中能够快速、方便地进行操作。
本课题针对“30米跨度幕布悬挂系统”进行设计,以满足船模拖曳试验中红外测试的要求。设计的幕布悬挂系统需要具备轻质、稳定、可调节和方便安装与撤收的特点。主要技术要求包括选择轻质幕布,幕布背面反光率和正面吸光率均不低于90%,形成的红外“暗室”长度不小于30米,宽度不小于8米,幕布底部距离水面高度在1至3米范围内可调。此外,四根立柱和安装在立柱上的滑车等设备无需撤收,其余物品包括钢缆和幕布等能较为方便的安装展开和撤收。最后,幕布系统安装展开时间不大于10小时,撤收时间不大于5小时。本课题的研究成果将为船模拖曳试验的红外测试提供技术支持和解决方案。

Abstract
The curtain suspension system of the ship towing system is a key equipment, which is mainly used in the ship towing test to provide the necessary support and protection for the ship towing system and meet the specific test needs. The following is about the ship model towing system. The main function of the curtain suspension system is to support and protect the ship mold, while providing the necessary stability and operation convenience for the ship mold. In the towing test, the curtain suspension system needs to be able to withstand the weight of the mold and provide sufficient support to ensure the stability and safety of the ship on the water surface. In addition, the curtain suspension system also needs to be easy to install and withdraw, so as to operate quickly and conveniently in the test.
This project is designed for the "30 m span curtain suspension system" to meet the requirements of the infrared test in the ship mold towing test. The designed curtain suspension system needs to be lightweight, stable, adjustable and easy to install and withdraw. The main technical requirements include the selection of light curtain, the reflection rate of the back of the curtain are not less than 90%, the length of the infrared "dark room" formed is not less than 30 meters, the width is not less than 8 meters, and the height of the bottom of the curtain is within the range of 1 to 3 meters. In addition, the four columns and the pulley installed on the column and other equipment do not need to withdraw, the rest of the items including steel cable and curtain can be more convenient installation and expansion and withdrawal. Finally, the curtain system installation and deployment time is not more than 10 hours, and the withdrawal time is not more than 5 hours. The research results of this topic will provide technical support and solutions for the infrared test of ship model towing test.
