Description

Aerocar serving ocean engineering test pool Technical Field The utility model relates to the technical field of ocean engineering experiments, in particular to an aerocar serving an ocean engineering test pool. Background In the field of ocean engineering, with continuous exploration and development of deep sea resources, design and performance evaluation of structures such as ships, ocean platforms and the like are particularly important. These structures are subjected to complex and varying stormy waves in the actual ocean, and therefore simulating these extreme conditions for testing and verification in a laboratory environment is an indispensable aspect. In order to achieve the aim, the construction of the test pool is one of the infrastructures of ocean engineering research, and a controllable experimental environment is provided for scientific researchers so as to deeply study the influence of storms and waves on ocean structures. In test ponds, the X-Y trailer arrangement plays a critical role as a key experimental device. The device not only can realize the towing of the ship model in the pool, but also is convenient for test personnel to measure and collect data, and is an indispensable important tool in ocean engineering experiments. However, with the continuous penetration of ocean engineering research and the increasing experimental requirements, the conventional X-Y trailer device has been difficult to meet the current experimental requirements in design. Particularly in stormy waves combined deep water laboratories, X-Y trailers face more stringent challenges. First, because laboratory ponds are typically equipped with large wind tunnels above, the space height of the test area is severely limited, requiring that the trailer assembly be adaptable in truss height to reduce the overall height to accommodate the small laboratory space. Secondly, in the wind-wave combined experiment, the drag problem of the trailer device in the wind field is particularly remarkable. Traditional trailer structure, like case roof beam structure or case roof beam adds truss hybrid structure, because positive resistance is too big, produces the scroll in the wind field easily, leads to the structure wind speed inequality about, and then seriously influences measuring result's precision. In addition, the larger wind resistance can also increase experimental energy consumption, improve experimental cost, and is unfavorable for long-term performance of experiments. Finally, considering that the trailer device needs to bear the influence of larger spans and wind loads in experiments, the rigidity requirement of the trailer device is correspondingly improved. Traditional trailer structures are often difficult to design to meet the requirements of low height, low wind resistance and high rigidity at the same time. Disclosure of utility model The utility model aims to provide an aerocar serving a marine engineering test pool, which realizes high-efficiency operation and low wind resistance under a low altitude space by optimizing structural design, and ensures enough rigidity to bear the influence of wind load and pool span.
