[Presentation overview]
In the development of the coil, electrical characteristics are designed using CAE or magnetic circuit simulation.
Using JMP's experimental design (SpaceFilling design), model creation (Gaussian process model), and simulator function of JMP prediction profile, the process capability index (Cpk) is optimized to shorten the design time and create a robust design. Aimed at high quality product design by
However, when the factor range of the experimental design is wide, there are cases where there are few experimental points in the product specification range, and it was found that there is a problem in the estimation accuracy.
Therefore, in order to efficiently improve the estimation accuracy, in the first stage, the optimum value is obtained over a wide range, and in the second stage, the range is narrowed down to the vicinity of the first stage's optimum value, and the final optimization is performed. It was investigated.
By this method, it was possible to obtain the optimum design value with higher accuracy.
