Optimization of reluctance motor with printed rotor

A novel way of optimizing a reluctance motor with rotor manufactured by 3D printing technology is presented. The optimization algorithms must take into account the tolerances of its production that are generally higher compared with classical processing, which requires a high level of&#...

Calibration of laser welding model based on optimization techniques

Purpose – The purpose of this paper is to present the calibration of a laser welding model suitable for solving problems with input data that are either unknown or known only approximately. Design/methodology/approach – The calibration starts from the measured temperature profile&#...

Magnetic forces behind hyperelastic behavior of magnetorheological elastomers

A magnetic and nonlinear structural mechanic coupled problem is discussed concerning the behaviour of a magnetorheological elastomer. Material properties and hyperelastic character of the material were found by measurements. Based on the measurements and computations, a coupled mathematical model is&#...

Optimization of selected electroheat models based on calibration of material properties

A novel technique of optimizing selected models of electroheat processes (laser or induction-assisted laser welding, cladding, and so on) is presented, based on the calibration of temperature-dependent material properties. These properties often exhibit uncertainties that negatively influence the quality&#...
