Abstract

The invention provides a method for evaluating the service life of an aviation motion hinge mechanism under a corrosion condition and a test device thereof. The method comprises the following steps: S1, constructing a corrosion coupling damage mechanism model through a material-level test; S2, simulating a corrosion environment experienced by the movement mechanism in a service period, accumulating part-level coupling damage test data, and optimizing the model; and S3, carrying out life evaluation on the aviation motion hinge mechanism in combination with test data. The invention also provides a test device capable of realizing large-angle rotation. The test device comprises an electromagnetic pressure regulating valve, an electromagnetic reversing valve, an angular displacement sensor, a tested hinge, a test fixture, a motor, an energy accumulator, a corrosive humid and hot environment test box and a control circuit. According to the invention, a mode of pressure regulation and electromagnetic valve double-control motor is adopted, so that the service life test device can meet the requirements of long-time, high-precision and large-swing-angle motion and the like, can effectively support the service life evaluation work of the aviation motion hinge mechanism under a corrosion condition, and provides accurate data support for the service life evaluation work.
