Abstract
A thermoelastic actuator for accurate settings of position is analyzed. Its mathematical model consisting of three partial differential equations is solved numerically in the hard-coupled formulation. The results (time evolution of the average temperature and dilatation of the working element) are compared with the data obtained by measurements on an experimental prototype of the device. Some disagreements between the results became the reason for a calibration of the model and its physical properties using an appropriate iterative process.
