Calculation Cost Reduction Method in Multi-Objective Optimization Using Machine Learning: Case Study on Actuator Development

Tomohiro Kuroda


Because multiple characteristics are maximized in the development of electromagnetic actuators, although modeFRONTIER (JMAG + multi-objective optimization) being a conventional tool still sees continued usage, however, there has been the issue of large calculation costs in situations where the required specifications (mounting space, etc.) repeatedly see several changes.
In this presentation, the relationship between design parameters and characteristics is first constructed as a predictive model by incorporating the results calculated with modeFRONTIER and JMAG into machine learning. We were then able to speed up calculations by using this predictive model in optimization calculations, and we show a case study for reducing calculation costs significantly in this presentation.
