摘　　要：以某驾驶室悬置为研究对象,基于三维软件UG建立几何模型,以Hypermesh软件建立有限元分析模型,并应用ANSYS软件进行模态分析,求出了某驾驶室悬置前六阶固有频率及相应振型,对各阶频率进行了分析,可为该车型驾驶室悬置系统的结构优化设计提供理论参考。Taking a cab suspension as the research object, its geometric model is established based on the three-dimensional software UG. Then the software Hypermesh is used to build its FEA model and ANSYS software to its modal analysis. The first six order natural frequencies and mode shapes of the cab suspension are obtained, and the frequencies are analyzed. The proposed results can provide a theoretical reference for the structural optimization of the cab suspension system.
