Problems solved by technology
[0004] Although the above-mentioned fixtures can be used for tension-compression fatigue tests, none of them have comprehensively considered the anti-corrosion performance of the fixtures in terms of structural design and protection process design according to the use characteristics of the tension-compression fatigue test fixtures under severe marine environmental conditions, and it is difficult to apply to marine outdoors. Long-term tension-compression fatigue test in atmospheric environment
At the same time, some fixture structures are relatively complex, and some fixtures have poor versatility. They can only be tested for specific types and sizes of specimens, and cannot be directly applied to pull flat and bar specimens in marine outdoor atmospheric environments. Pressure fatigue test

The invention discloses a marine outdoor atmospheric environment tension and compression fatigue test fixture and a test method thereof. The clamp comprises an upper clamp body and a lower clamp bodywhich can be arranged on the fatigue testing machine and are opposite to each other up and down, an upper clamp pressure plate is adjustably positioned below the upper clamp body through an upper locking bolt, an upper test piece clamping block is arranged between the upper clamp pressure plate and the upper clamp body, and the upper test piece clamping block and the upper clamp pressure plate aremovably arranged in a wedge shape; a lower clamp pressure plate is adjustably positioned above the lower clamp body through a lower locking bolt; a lower test piece clamping block is arranged betweenthe lower fixture pressure plate and the lower fixture body; wherein the lower test piece clamping block and the lower clamp pressure plate are movably arranged in a wedge-shaped manner, each part adopts various protective layers to carry out anti-corrosion protection on the marine atmospheric environment, and the continuous and effective test of the tension and compression fatigue test in the marine outdoor atmospheric environment is improved by combining the clamping mode of the test piece.
Description
technical field [0001] The invention relates to a jig for tension-compression fatigue test in an outdoor marine atmospheric environment and a test method thereof, which are used for long-term tension-compression fatigue tests of auxiliary equipment or products in an outdoor marine atmospheric environment, and belong to the technical field of environmental testing. Background technique [0002] When equipment (products) are used in harsh and complex marine and atmospheric environments, they will withstand the combined effects of severe marine and atmospheric environment corrosion and tension / compression loads, which will bring great benefits to the safe and reliable use of critical structures of equipment (products). Hidden dangers, especially will aggravate the corrosion fatigue damage of critical load-bearing structures mainly made of high-performance structural steel, aluminum alloys, titanium alloys, magnesium alloys and other metal materials, and accelerate their performa...
