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 2.5 Mpa 水压，具备 1.8 cm/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 25 kg 压载下经 24 h 支撑杆仅发生 0.5 mm 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 is optimized and proposed. A detailed technical design is carried out， and the principle prototype is developed. The test results show that the prototype can withstand water pressure of 2.5 Mpa with support rod expansion rate of 1.8 cm/s. Its roll adjustment ability is bigger than 10° and it has good position keeping ability. Under a ballast of 25 kg，the position change of the support rod is only 0.5 mm after 24 h. The prototype is equipped on an existing UUV for sea trial，and the support function is demonstrated. The research results provide a new idea for underwater bottom-sitting technology.
