摘要
汽车座椅骨架的固有频率和振型是其动态特性设计中的重要参考指标,本文利用三维建模软件Proe建立某汽车座椅骨架三维模型,基于有限元分析软件Workbench对其进行模态分析,得到其前十阶固有频率值和振型,并对结果进行了分析。
The natural frequencies and mode shapes of an automotive seat frame are an important reference index of its dynamic design. Its three-dimensional modal is established by Proe software. The previous ten natural frequencies and mode shapes are got based on Workbench and the results are analyzed.
