Induction-assisted laser welding taking into account phase changes

Purpose – The paper aims to describe the modeling of the induction-assisted laser welding process taking into account the keyhole effect and phase changes in the material. Design/methodology/approach – A sophisticated mathematical model of the above heat treatment process is presented,&...

Positioning uncertainty reduction of magnetically guided actuation on planar surfaces

Key design and operation parameters of the system for magnetically guided actuation of miniature robots on planar surfaces are analyzed and discussed. The study is carried out on the numerical analysis and also on the experimental measurement on the prototype of the system. Special...

Applicability and comparison of surrogate techniques for modeling of selected heating problems

Possibilities of using surrogate techniques for modeling selected strongly nonlinear coupled problems of heating are evaluated. The main purpose is to significantly reduce the computing time in the case of computations of many variants of a given task by the finite element method o...

The representation of some phrases in Arabic word semantic vector spaces

Design of electrical machines with low carbon footprint is an actual topic in the industry. Total cost of ownership is the standardized methodology to consider the lifetime costs of a power transformer already in the pre-concept design stage. There still does not exist a widel...

Micromechanical analysis of fiber spatial distribution influence in unidirectional composite cross-section on overall response in terms of tensile curves

Accurate temperature control is an important part of an induction brazing process, because of a small difference between melting points of aluminum and soldering material. However, direct measurement of the local temperature at the spot of brazing is not possible in a production li...
