| Abstract(J) | EVの普及によりインバータ由来の高周波音が新たな課題となっている．従来はFEMとSEAにより予測が行われてきたが，SEAはモデル構築に手間を要するため設計上流には適さない．そこで本研究では音線法を適用し，上流設計における計算負荷と解析精度のトレードオフを効率的に達成するための指標を提示することを目的とする． Translation |
| Abstract(E) | With the spread of electric vehicles, it has become necessary to address high-frequency noise generated by inverters. Since FEM is generally impractical for acoustic analysis in higher frequency ranges, analytical SEA has traditionally been employed as an alternative approach. However, SEA is not suitable for upstream design due to the time-consuming of its model construction. Therefore, sound ray tracing which has been developed primarily in the architectural acoustics field was applied, and aims to propose a guideline for efficiently balancing the trade-off between computational cost and analysis accuracy in upstream design. |
