| Abstract(J) | 足回りへの加振入力を，ロードノイズを放射する車体フロアーパネル振動へと伝達する車体骨格について，その伝達過程の理論的な考察を行った．単純な上下・前後入力が，骨格の曲げやねじりの複合振動に変化する機構を，骨格断面形状に依存するウォーピングや，断面でのせん断流の考慮で説明し，改善設計の方向を示した． Translation |
| Abstract(E) | Theoretical study was conducted on the process that vehicle body members transform the vibration input to the suspension to the vehicle body floor panel vibration that radiates road noise. Consideration of warping and shear center offset were found to be able to explain the process in which simple vertical and/or back and forth excitation inputs change to combined bending and torsion vibration of the body structural members. This study showed the direction of road noise design improvement. |
