水下航行器液压式坐底支撑机构研究

Research on hydraulic bottom-sitting support mechanism of underwater vehicle

摘要:

针对水下无人航行器着陆坐底的需求,优化提出一种液压支撑杆式坐底辅助机构,进行了详细的技术设计并形成原理样机。经测试,该样机可耐2.5Mpa水压,具备1.8cm/s的支撑杆伸缩速率,高于10°的横倾调节能力与良好的位置保持能力,在25kg压载下经24h支撑杆仅发生0.5mm的位置变化。而后,将该样机配装于已有航行器进行了海试验证,验证了支撑功能。研究成果为水下坐底技术提供了新思路。

Abstract:

In order to meet the requirements of underwater unmanned vehicle(UUV) landing, a hydraulic support rod type bottom auxiliary mechanism was optimized and proposed. The technical design was carried out in detail, and the principle prototype was formed. The test results show that the prototype can withstand 2.5Mpa water pressure, has 1.8cm/s support rod expansion rate and has a roll adjustment ability of 18°. Under 25kg ballast, the position change of only 0.5mm occurs after 24h. Then, the prototype was fitted to an existing vehicle and the sea trial was carried out to verify the support function. The research results provide a new idea for underwater bottom-sitting technology.
