“…The formula synthesis is based on the regression models [11]. This work was further developed for engineering calculations [12] and so the methodology is successfully used for synthesis in the electrical machine field [13,14]. The works of A. G. Ivakhnenko [15] determine the ideological criteria and the base of synthesis models.…”

In this paper the influence of basic design parameters (proportionality coefficient β and permanent magnets height h) on the mechanical torque for cylindrical magnetic coupler with rounded permanent magnets is researched. Such cylindrical magnetic couplers are often used in pumps and liquid mixers. At the beginning the design parameters and their relevance are explained. The mechanical torque is calculated applying the software QuickField. In the data analysis and for the coupler comparison the division of maximal mechanical torque on volume is taken as the main characteristic. Because of the planned optimization for the calculated variants there were synthesized few formulas, from which the most suitable were found (for all researched design parameters’ ranges). The formulas are synthesized using a program, which is created by Oskars Onzevs. The program for the formula synthesis is based on regression models, and the basic principles of it are explained. All the calculations for experimental and formula data are made for magnetic coupler’s design with one pole pair number p that is equal to three.

“…In the development stages of various machines, constructions and complex mechatronic systems, computer modelling with the aim of detailed investigation and improvement of their properties is becoming more and more widespread. In the field of mechanical engineering, the so-called virtual prototyping tools, that is software [ 1,2 ] that allows to create automatically mathematical models of mechanical systems to estimate their dynamic and strength properties and carry out their parametrical optimization, are widely used. By that, one is frequently faced with the global optimization task.…”
