- Summary, etc.
- The accuracy and reliability of FE models become more important to realize the virtual engineering. Thus, the quality of structural FE models such as white-body models is also required to be enhanced. From the investigation, it showed that natural frequencies derived by the simulation results of the general FE models are higher than experiment data. The drawing information is the basis of normal FE models construction, and it have issue to represent the experiment. The information from the production process like stamping effect can enhance the quality of the FE models. This paper describes the calculation results of stamping simulation have been applied to the FE models for NVH analysis. As the results, the gaps of natural frequencies between NVH analysis and the experiment can be closer with small errors.正しくNVH事象解析, 性能検証するためCAE信頼性向上に取り組んだ.自動車は量産品で各個体ごとに性能ばらつきがあるが, 全個体の共通要素を詳細にモデル化する観点でBIW CAEモデル手法を見直した．BIWモデルにプレス加工影響を反映すると実験結果との相関が改善し, 目的に見合ったモデル信頼性を達成できた.
