| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a vehicle front part structure that suppresses vibration of a cabin without causing constraint in manufacturing, such as increase in the number of components and vehicle weight.SOLUTION: In the vehicle front part structure, adjusting shapes of beads 72A, 72B of a radiator support upper member 30 matches mount positions of front side members 12A, 12B of radiator support side members 28A, 28B with node positions of vehicle width direction vibration of the radiator support side members 28A, 28B in a frequency band containing a natural frequency of a vehicle body, thereby suppressing a vibration amount of the front side members 12A, 12B to suppress vibration of the cabin.SELECTED DRAWING: Figure 1
【課題】部品点数や車体重量の増加等の製造の制約をもたらすことなく、車室の振動を抑制する車両前部構造を提供する。【解決手段】ラジエータサポートアッパメンバ３０のビード７２Ａ、７２Ｂの形状を調整することにより、ラジエータサポートサイドメンバ２８Ａ、２８Ｂのフロントサイドメンバ１２Ａ、１２Ｂの取付位置と車体の固有振動数を含む周波数帯におけるラジエータサポートサイドメンバ２８Ａ、２８Ｂの車幅方向振動の節位置とを一致させることによって、フロントサイドメンバ１２Ａ、１２Ｂの振動量を抑制して車室の振動を抑制する。【選択図】図１ |
