电力机车振动模型的建立及振动分析

Building model and analysis vibration of electric locomotive

为了更好地评价轨道不平顺差异等引起的车体结构扭振和侧振 ,利用直接积分的瞬态特性分析和特征值分析 ,建立了三维有限元车体结构模型 ,用其对韶山SS8型机车进行振动分析 ,结果与实际吻合很好 .

In order to ideal value the vibration of torsion and flank roll which result in the track smooth difference,3D FEM(fiaite element method) model of locomotive is built by the analysis of transient state eigenvalue of direct integral,it is used to make analysis vibration of Shaoshan SS8,the result is in coincidence with real vibration.
