The high and low temperature fatigue testing machine is mainly used to evaluate the physical fatigue performance tests of various materials, components, parts, springs, rubber, etc. in high and low temperature environment, such as tension, compression, bending, shearing, low cycle, high cycle, low frequency and high frequency. The complex stress state of the material in practical use is simulated by applying periodic loads with different performance, and it can be tested under different temperature conditions. Applicable to: aerospace, auto parts, elastic parts industry, railway, quality inspection research, universities and colleges, etc.
