Experimental Analysis and Construction of Measurement Model for Torque Calibration Device in Variable Temperature Environment

The article introduces the design structure and principle of a torque calibration device in a 5kNm variable temperature environment. By constructing a measurement model, it quantitatively analyzes the measurement uncertainty of the device and conducts calibration tests on standard torque sensors. The results indicate that the designed device can provide theoretical foundations and a basis for the traceability of torque sensors in variable temperature environments
