某型全地形车车架动态特性分析
Dynamic Characteristic Analysis of an All-Terrain-Vehicle Frame
摘要
Abstract
In view of the running process of the ATV and its structural feature,a computer aided design model is built using UG and a finite element method model is created using Hypermesh.The software-Altair HyperWorks, together with the modal testing and analysis system-LMS, are individually used to separately conduct the analytic modal analysis and experimental modal analysis. The results indicate that after the frame with modal analysis:the finite element model and modal analysis results are accurate and reliable.Finally,the influence of the road roughness and the engine excitation on the dynamic characteristics of the vehicle frame is analyzed,and it is found that the excitation of the engine is most likely to cause the resonance of the frame structure.关键词
