基于HyperWorks的车身地板的有限元分析

The Vehicle floor FEA based on the HyperWorks

以某车型的车身地板模型为例，利用有限元分析软件HyperWorks中的HyperMesh模块对车身地板进行网格划分，运用Optistruct模块对其进行模态分析，分析其固有频率及振型。目的是为了使汽车的结构在设计中尽量避免共振和噪声，加强其稳定性和安全性，也为实际生产提供了参考和依据。

Taking the modular vehicle floor design as an example, by means of the HyperMesh Module of the FEA analysis HyperWorks software to divide the vehicle floor. By means of the Optistruct Module to analyze the native frequency and the vibration. In order to avoid occurring the noise and the resonance during the automotive structure design, intensify the stability and reliability and provide the reference and the accordance for the actual production.
