Abstract

The invention relates to an airbag loading device, which comprises a frame provided with a pressure sensor, air bags, a guide rail, a sliding block pair, an air source, and a controller. the number ofthe air bags is at least two, the air bags are sequentially overlapped and connected to form an air bag set, one end of the air bag set is connected with the frame through a pressure sensor, and a transmission plate is arranged at the other end of the air bag set; one end of the guide rail is connected to the frame, and the other end of the guide rail extends towards the overlapping direction ofthe air bags; the sliding block pair is arranged on the guide rail in a sliding mode, and the sliding block pair is connected between the air bags in a transmission mode; the air source is connected with the air bags, and direction flow valves are arranged between the air source and the air bags; and the direction flow valve and the pressure sensor are respectively connected with the controller through signals. And the requirement of large deformation quantity of the measured piece can be met. The device is applied to the technical field of measurement.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to an airbag loading device. Background technique [0002] The airbag loading device is mainly used in the static or dynamic (fatigue) loading test of test components such as aircraft fuselage, wing or vertical tail. [0003] The airbag recording device in the prior art is a single airbag, and the load loading of a single airbag is limited by its own structural size, which can only be adapted to the working conditions of the small deformation of the tested part after loading. When the test piece is loaded in the test, it cannot provide a stable pressure loading value and cannot meet the use requirements. [0004] Therefore, the inventor provides an airbag loading device. Contents of the invention [0005] (1) Technical problems to be solved [0006] The embodiment of the present invention provides an airbag loading device, which solves the technical problem that a stable pr...
