Embodiment 1
[0016] Such as Figure 1-3 As shown, a steel bar-supported oscillation test mechanism based on a horizontal opening wind tunnel includes a model support device, a main frame and two sets of driving devices. The main frame is fixedly installed on the upper and lower turntables of the horizontal opening wind tunnel test section. The turntable performs side-sliding movement, and the two sets of driving devices are symmetrically fixed and installed on the two side pillars of the main frame. The model support device is connected to the power output end of the two sets of driving devices. The detection unit ensures that the driving devices on both sides move synchronously; the model supporting device includes two sets of cross-shaped main rods, 8 main steel rods and hanging components, and the center of each cross-shaped main rod is connected with the power of the driving device. The output end is connected, each cross end of each set of cross-shaped main rods is connected to one en...
Embodiment 2
[0018] Such as figure 1 As shown, the model supporting device includes a hanging assembly 1, 8 thin steel rods 2, a plurality of tight nuts 3, a plurality of adapter shafts 4, a plurality of ball joints 5, a plurality of ball joints 6, and a plurality of extension rods 7 , 2 sets of cross-shaped main poles 8, 2 sets of rotating shaft joints 9, multiple supporting steel rods 19, multiple snap rings 22, multiple supporting steel rod lock nuts 20 and multiple supporting steel rod adapter shafts 21. One end of the main steel rod 2 is connected to the ball socket of the suspension assembly 1 through the ball head at the front end of the steel rod, the other end is connected to the main steel rod lock nut 3, and the end of the main steel rod lock nut 3 is connected to the main steel rod transfer shaft 4 Connection, in order to adapt to the angle difference during the installation process of the mechanism, the main steel rod transfer shaft 4 is connected with the ball joint 5 with an...
