Embodiment 1
[0021] See attached Figure 1-6 As shown, a clipping panel device in the test section includes a panel frame, an inner layer plate 28, a shifting plate 29, a driving mechanism, a position feedback system for the shifting plate, a pressing mechanism and a guiding mechanism; the panel frame Including longitudinal rib 4 and transverse rib 6, the surface of longitudinal rib 4 is higher than the surface of transverse rib 6, longitudinal rib 4 and transverse rib 6 are connected by welding; the drive mechanism includes support shaft 1, flange 2, electric cylinder 3, ear seat 5, swing arm 7, tie rod seat 12 and tie rod 14; the ear seat 5 is fixedly connected to the transverse rib 6 of the panel frame, the electric cylinder 3 is internally integrated with a servo motor, and the front end of the electric cylinder 3 is hinged to the pendulum through the first pin shaft 8 On the arm 7, the rear end of the electric cylinder 3 is hinged on the lug 5 through the second pin shaft 9, the lower...
Embodiment 2
[0028] Working process and principle of the present invention are:
[0029] After the wind tunnel test starts, the airflow flows through the test section, and there will be a certain pressure difference inside and outside the test section. When the force generated by the pressure difference is enough to push the staggered plate 29 away from the inner plate 28, a group of evenly distributed pressing mechanisms The force generated by the pressure difference is offset, and the two-layer board remains in a state of bonding throughout the test. When the holes of the inner layer plate 28 and the shifting plate 29 are all or partly communicated, part of the air flow enters the chamber through the holes on the wall plate, and the thin metal sheet provided in the inner layer plate 28 holes reduces the noise of the air flow. According to the test requirements, control the rotation of the swing arm of the driving mechanism in the corresponding area, pull the rod seat 12 and the shift pla...
