Abstract
Belonging to the technical field of inflatable deployable radial rib antennas, the invention relates to a rib plate tension experimental device for an inflatable deployable radial rib antenna, and solves the problem of lack of device for tension experiment on a rib plate at present. The experimental device includes a clamping piece and pulleys. The clamping piece comprises an upper clamping piece and a lower clamping piece, and the upper clamping piece and the lower clamping piece are parallelly disposed opposite to each other and are slidably connected to a rear support. The front edges of the upper clamping piece and the lower clamping piece are both arc-shaped, a plurality of round holes are correspondingly disposed near the front edges on the upper clamping piece and the lower clamping piece. The pulleys are slidably connected to a front support, the number of the pulleys is identical to that of round holes on each clamping piece, each pulley is disposed toward a round hole, and all the pulleys are connected to the lower surface of one arc-shaped cross beam. The front support and the rear support are in fixed connection through a plurality of connecting rods. The device provided by the invention is used for rib plate tension experiment of the inflatable deployable radial rib antenna.
