Simulation Analysis of Tensile Testing Machine at Deep Low Temperature Based on ANSYS
Aiming at the problem of tensile mechanical property testing of metal materials in vacuum deep low temperature environment,a kind of tensile testing machine which can be used in vacuum deep low temperature environment is designed.The testing machine is built into the vacuum chamber.The G-M two-stage refrigerator is used as the cold source,and the sample is cooled by heat conduction.In order to verify the reliability and safety of the device,the finite element analysis software is used to analyze the strength of the device.In order to ensure that the samples can achieve the deep low temperature condition,the finite element analysis software is used to carry out the steady-state thermal analysis of the samples.The results of simulation analysis show that the structural design of the device is reasonable and the sample temperature can meet the requirements,which provides theoretical support for the design of the device.
