摘要
结合工程实例,对铁路货运车辆疲劳与振动试验台的基础进行了设计分析.通过现场实测得到桩基动力特性参数,根据相关标准算出振动频率分别为3 Hz、10 Hz、20 Hz、30 Hz时基础顶面的振动位移,并与有限元分析结果进行了对比.
Abstract
The foundational structure of the fatigue and vibration test bench for railway freight vehicles is meticulously scrutinized,with dynamic characteristic parameters of the pile foundation obtained through rigorous field measurements.Subsequently,employing prescribed standards formulas,the vibration displacement of the foundations top surface is calculated at discrete frequencies(3Hz,10Hz,20Hz,and 30Hz),followed by a comparative analysis against finite element analysis results.
