A cryogenic testing system with a cryostat and a refrigerator for a biaxial testing machine was developed to evaluate mechanical properties of composite materials under biaxial mechanical and cryogenic thermal loads. In this report, cooling characteristics of the cryogenic testing system were numerically evaluated with heat conduction analysis by the finite element method. Simplified numerical calculation without temperature dependency of material thermal constants approximately simulated the cooling characteristics of the cryogenic testing system compared with the measured temperature data. Effects of heat generation by strain gauges and testing material (composite, aluminum alloy, or stainless steel) on the cooling characteristics were evaluated for the purpose of future cryogenic testing designs.
