摘要
为保证水下拖曳系统快速安全地释放回收拖体,设计了一种采用开式容积式调速回路的拖体收放电液比例系统,满足了水下拖曳系统独立收放拖体和同步收放拖体这两种工况的要求。建立了同步收放拖体即拖缆卷筒和收放架同步工作时电液比例系统的数学模型,提出了基于结构不变性原理的同步控制策略,补偿拖缆卷筒液压马达因速度变化引起的拖缆张力波动,保证了拖体同步收放的顺利进行。实验表明,所设计的拖体收放电液比例系统性能优异,同步控制策略具有较好的控制性能。
A towed body launch and recovery electro-hydraulic proportional system with volumetric speed control open circuit was designed to make a underwater towed system release and retract the towed body rapidly and safely. The electro-hydraulic proportional system meets the needs of independent or synchronous operating of towed body. When the towed body is released or retracted synchronously, a cable winch and a crane of underwater towed system operate simultaneously. A mathematic model was built for the electro-hydraulic proportional system. A synchro-control strategy based on structure invariance principle was proposed to compensate the tension fluctuation of cable due to velocity variation of cable winch driven by hydraulic motor and assure the trouble-free execution of synchro process. The experimental results show that the electro-hydraulic proportional system and the synchro-control strategy both have good control performance.
