摘 要: | 通过对处于产品设计阶段的新型农用运输车车架的结构分析,建立了有限元模型,用MSC/NASTRAN软件,进行了模态分析,给出了相应的主振型及频率。分析的结果对整车及各部件振动的频率区段的划分有着重要的指导意义,并为车架结构的改进设计提供了理论依据。

Modal Analysis for Farm Transporter Frame |
| |
Abstract: | ?Based on the analysis of the new type farm transporter's frame construction.the finite element model is developed. By means of the soft ware MSC/NASTRAN,the main model and the corresponding frequency are obtained through the modal analysis. The analysis results are very important for determining the frequency band's distribution among the components and provide the theory basement for the frame improvement |
