本文中运用ANSYS软件, 建立了六轴车架的实体模型, 通过对其进行网格划分,做出了车架的有限元模型,通过ANSYS软件的计算模块计算了油气弹簧悬架在等刚度时的20阶模态,和油气弹簧悬架在等轴荷时的20阶模态,求出车架的固有频率及振型特征,为汽车的结构在设计中尽量避免共振和噪声, 加强其稳定性、舒适性和安全性, 同时也为实际试验提供了参考和依据。

The software wielding ANSYS in the main body of a book, has built a six scroll of the carriage entity model , has divided by carrying out the net lattice on the person, have made the carriage finite element method model out, that spring having calculated an oil gas by ANSYS software calculation module is unsettled when waiting for stiffness the rack 20 order is a modal and oil gas spring is unsettled when waiting for the axis lotus the rack 20 order is a modal and , seek out the carriage natural frequency and shake the type characteristic, be that the automobile structure tries one's best to avoid resonance and noise in design , reinforce whose stability , comfortableness and security , be that the actual experiment has provided the reference and the basis at the same time also.
