Abstract

The invention relates to an inflation fatigue test loading device, aiming at solving the technical problems in the technical field of existing aeronautical engineering that fatigue damages are easy to generate by a structure influenced by inner and outer pressure difference. The inflation fatigue test loading device comprises a filter, reducing valve and lubricator (FRL) part, a two-position three-way solenoid valve, a three-position five-way solenoid valve, a pipeline throttle valve, a three-position five-way solenoid valve, a safety valve and a ball valve; the two-position three-way solenoid valve is connected with the filter, regulator and lubricator part through a pipeline; the three-position five-way solenoid valve is connected with the two-position three-way solenoid valve through a pipeline; the ball valve is connected with the three-position five-way solenoid valve through a pipeline; the safety valve is mounted on a front end pipeline of the ball valve; an input end of the pipeline throttle valve is connected with a pipeline at the front end of the three-position five-way solenoid valve; an output end of the pipeline throttle valve is connected with the input end of the three-position five-way solenoid valve; the output end of the three-position five-way solenoid valve is connected with a pipeline at the rear end of the three-position five-way solenoid valve. The inflation fatigue test loading device is widely applied to the technical field of the aeronautical engineering.

Description

technical field [0001] The invention relates to the technical field of aeronautical engineering, in particular to an inflatable fatigue test loading device. Background technique [0002] In the field of aeronautical engineering technology, many structures, such as the internal and external pressure difference of aircraft cabins, are constantly changing, which is equivalent to applying periodic air pressure loads to the cabins. The long-term effects of these air pressure loads will cause fatigue damage to the structure, and then Structural failure occurs, so from the perspective of aviation safety, it is necessary to carry out pneumatic fatigue loading tests on these structures to determine the weak areas of the structure and improve the design. How to test it has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In order to solve the technical problem that the structure affected by the internal and external pr...
