Abstract
The invention discloses a wind tunnel test model assembly and disassembly assistance system comprising a movable model part and a second connecting substrate mounted thereon, a fixed model part and a first connecting substrate mounted thereon. A screw is arranged between the two connecting substrates. The thread directions at the joints of the screw and the two substrates are different so that the rotation of the screw drives the two connecting substrates to move to each other. According to the invention, the thread directions at both ends of the screw are different from each other and the thread directions of the two substrates are also different from each other so that the two substrates can be moved in the same direction or in the opposite direction when the screws are rotated in different directions. The various parts of the wind tunnel test model assembly and disassembly assistance system are simple in appearance, convenient in installation and simple in operation. An actual operation shows that the assembly and disassembly of the wind tunnel test model becomes time-saving and labor-saving and does not cause any damage to the model.
