角板对8m客车顶盖骨架固有频率的影响

Influence of bracket joints on 8m-long bus roof frame's natural frequency

以某8 m客车顶盖为例,通过ANSYS软件进行模态分析,探讨了角板对客车顶盖骨架固有频率的影响。结果表明,增加角板对于顶盖骨架的固有频率影响较小。

With an example of 8 m-long bus roof frame, the influence of bracket joints on bus roof frame＇s natural frequency was discussed using modal analysis based on ANSYS software. The computation indicates that increasing bracket joints exert a relatively small influence on bus roof frame＇s natural frequency.
