“…Makoto et al have identified parts of the transmission case, which are related to noise, by sensitivity analysis and improved the structure of the transmission case [11]. Dai et al performed topographical structural optimization to reduce the sound power by reducing the velocity of the surface in transaxles [9]. Thus, the finite element method (FEM) is utilized for optimization of the transmission case in this research, because the calculation time of the acoustic power using the FEM is shorter than the BEM.…”

“…The analysis time of FEM is much faster than BEM [8]. Also, if we want to use a commercial system for optimization, the acoustic power cannot be directly selected as the objective function due to the limitation of the current commercial solvers [9].…”
