摘要
铁路货车牵引梁是轨道车辆运行过程中的重要系统部件,该部件受结构振动影响显著.通过有限元理论和频响理论相结合进行牵引梁有限元分析,基于模态叠加法对牵引梁做频率响应分析,获取牵引梁的变形频响曲线,同时关注固有频率对频响函数峰值的影响,从而使得频响分析结果更为准确.
Abstract
The traction beam ot a railroad wagon constitutes a critical component within the rail vehicle operation process.However,this component is significantly influenced by structural vibrations.Therefore,this paper employs a combination of finite element theory and frequency response theory to conduct a finite element analysis of the traction beam.Additionally,it performs a frequency response analysis using the modal superposition method to obtain the deformation frequency response curve of the traction beam.At the same time,we pay attention to the influence of natural frequency on the peak value of frequency response function,which makes the result of frequency response analysis more accurate.
