A novel possibility of accurate control of position is proposed, based on the thermoelastic effect. This paper presents the relevant device together with its complete mathematical model and methodology of its numerical solution. The theoretical analysis is supplemented with the description of the basic operation characteristics of the device.

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… (More)

The paper deals with the analysis of operation electromagnetic doser of molten metal in periodical regime. The doser is driven by three-phase current. There is presented the mathematical model and also the computer model. The focus of the work is to discuss the results of the numerical examples that enable to choose an optimal arrangement and operational… (More)

A complete model of a cylindrical induction shrink fit between the disk and shaft is presented. The model consists of two independent parts. The first part is aimed at the purely mechanical aspects of the shrink fit (determination of the interference between both parts necessary for transferring the prescribed torque and reduced stress in both parts for the… (More)

This work deals with numerical computation of effective impedance per unit length of profile conductors carrying harmonic currents for a wide range of frequencies (50 Hz - 50 GHz). The paper investigates, particularly, the influence of varying profiles of the conductors for the same surface of their cross-sections. The theoretical analysis is illustrated on… (More)
