Abstract：The distortion of engine intake temperature affects the stability of the engine, and small inertia thermocouples are usually used to measure its rapidly changing airflow temperature. In order to accurately and comprehensively obtain the dynamic characteristic of small inertia thermocouples, a dynamic characteristic calibration and evaluation method of small inertia thermocouples is porposed, and the construction of dynamic calibration device, calibration test and frequency domain analysis are introduced. The dynamic calibration method is combined with a pulse laser and a calibration wind tunnel, through the analysis of amplitude frequency characteristics and phase frequency characteristics, the evaluation method for the dynamic characteristics of small inertia thermocouples is expanded. Using this calibration method for dynamic calibration of small inertia thermocouples, the maximum relative uncertainty of type A reduces from 7.2% to 2.4%, which can be used for dynamic calibration of fast response temperature sensors below 30ms.It provides technical reference for high-frequency dynamic temperature measurement such as engine intake temperature distortion.
