汽车车桥的模态分析

本科论文AbstractIn order to deeply analyze the static vibration intensity and responsecharacteristics of a light truck bridge,the new finite element vector analysis method is usedto simulate its vehicle bridge.In this paper,a finite element analysis tool is used to analyzethe characteristics of three kinds of static motion strength of vehicle bridge structure underthree different working conditions by ANSYS,and the characteristics of three kinds ofdynamic strength characteristics of them are analyzed by free mode.The finite elementmethod is used to simulate its numerical value.That is to say,the mesh in static analysisand dynamic analysis can encrypt the local part,and the data of modal analysis is good andeven,reaching the ideal degree.From the data point of view,the static motion has reacheda reasonable level,which can ensure the performance requirements of the automobile axlein the design.Through the data analysis and experiment results,it is clear that the static anddynamic characteristics of the main structure of the axle and the changing characteristics ofthe force basically ensure a series of requirements in the design of the axle.So it can betterdesign the axle structure,and make it have good static and dynamic characteristics.Key words:ANSYS,bridge,finite element,modal analysis
