Abstract

The invention discloses a cooling device for high-frequency fatigue testing machine sample cooling. A vortex cooling pipe and an air compressor are included, wherein the vortex cooling pipe is used for providing cold air flow making a sample cooled for the sample, and the air compressor is used for providing compressed air for the vortex cooling pipe. According to the cooling device for high-frequency fatigue testing machine sample cooling, the vortex cooling pipe is arranged to provide the cold air for the test, the cooling effect is good, effective control over the sample temperature is achieved, and the test result accuracy is ensured. The invention further provides a cooling method for the high-frequency fatigue testing machine sample.

Description

technical field [0001] The invention belongs to the technical field of fatigue testing machines. Specifically, the invention relates to a cooling device and a cooling method for cooling samples of high-frequency fatigue testing machines. Background technique [0002] Under the long-term action of alternating load, the fracture caused by cumulative damage is called fatigue. Fatigue fracture is the main cause of failure of engineering components. Various fatigue tests have been carried out on various materials for a long time. Due to the long fatigue test cycle and low efficiency, people have developed a high-frequency fatigue testing machine. By increasing the frequency of the testing machine to shorten the test cycle and improve the test efficiency. The ensuing problem is that for plates and bars with larger thickness and diameter, as the test frequency increases, the sample has serious heating problems, resulting in distortion of the test results. Therefore, it is necess...
