| 摘 要： | 建立了某微型客车白车身结构的有限元模型，计算了在自由状态下该白车身结构的振动模态，并提出了鉴别整体模态与局部模态的方法。计算结果与试验结果进行了对比分析，结果表明所建立的有限元模型基本反映了原结构的振动特性。

Modal Analysis for Body-in-White of a Mini Bus |

| Abstract: | In this paper the finite element model of body-in-white of a mini bus is established.The vibration modes of body-in-white in unrestricted conditions are evaluated and a method is brought forward to identify the local modes and the modes of whole system.The computed results are compared with tests.It shows that the model has represented the vibration characteristics of the original structure. |
