Research on Testing Methods of Temperature Strain and Force Strain under Extreme Temperature Environment

Abstract

Abstract The traditional quartz differential method and the half-bridge connection temperature compensation test method are improved to realize the effective separation of the physical deformation of the material caused by the temperature effect and the deformation caused by the load under the coupling effect of temperature and load, so as to be the thermal expansion coefficient of the material at extreme temperatures And provide the basis for the test and determination of mechanical performance parameters.
