Embodiment Construction
[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0027] The problem to be solved in the embodiments of the present invention is that the width of the wedge in the prior art is difficult to change after it is manufactured, and local adjustment cannot be realized, and it can only be assisted by other auxiliary devices. This scheme will cause the problems of long test cycle and low test precision. In addition, the finished wedge can only satisfy the simulation of the wind speed profile under a single scale ratio. If the test is carried out under multiple scale ratios, it is necessary to make a wedge separately, which will increase the test cost.
[0028] Such as Figure 1-3 As shown, it is a schematic diagram of a passive simulation wedge device for adjustable wind ...
