The invention discloses an electrically-assisted forming pure electroplastic effect measuring device and method based on
contact type cooling. The device comprises a loading unit, an electrifying unit, a
contact type cooling unit, a measuring unit and a
control unit. The method is characterized in that a
friction force calibration experiment is carried out, and
system errors are quantified; then, under closed-loop
temperature control, electrifying, deformation and dynamic cooling are synchronously carried out, so that the temperature of the sample is stabilized at the target temperature to completely offset the
Joule heating effect; and finally, the measurement result is corrected based on the calibration data, the corrected electrified deformation data is compared with the thermal
baseline data, and the difference value is the accurate quantized value of the pure electroplastic effect. According to the device and the method, the high-thermal-
conductivity insulating
ceramic chip is adopted for
contact type cooling, the problem of material
chemical pollution caused by
liquid nitrogen injection is fundamentally avoided,
system errors caused by contact are eliminated through an original
friction force calibration and correction process, and in-situ, accurate and
nondestructive measurement of the pure electroplastic effect of the material is achieved.
