Development of a Kind of Fatigue Test Equipment for Cold Climate Environment

Objective To develop a kind of fatigue test equipment for cold climate environment. Methods Based on the service process of equipment materials under the coupling conditions of cold climate-tension, compression and bending load, interaction effects of environmental and mechanical factors were analyzed to determine working principles and function characteristics of the new equipment. Structure and reliability of the equipment were designed reasonably through analysis on working environment and characteristics of the equipment itself to design and develop a kind of fatigue test equipment for cold climate environment. Results The test equipment could accomplish precise control of test parameters such as load and frequency, and carry out the tensile, compression and bending test in the cold climate environment by changing the test fixture. Conclusion The newly developed equipment is suitable for investigating tensile, compressive and flexural properties of materials in cold climate.
