[摘要] 随着我国高速铁路的快速发展，高速、重荷载货运列车研究已全面铺开，足尺货车车辆研究将发挥越来越大的作用。在足尺试验研究中，货车试验台基础设计对于整个试验台的正常运行、数据采集至关重要。本文通过集总参数的模型对试验台基础进行了动力分析，并用MIDAS软件进行模态分析，验证了所设计基础体系的合理性。

Abstract: Research on lugh speed and heavy load train has been carried out with the fast development of lugh-speed railwayin our country. The full scale vehicles research plays more and more major role. Design of shaking table foundation is very important to the table's normal operation and the data acquisition. This article carried on dynamics analysis to the table foundation through lumped-parameter model. And then, using finite procedure MIDAS model analysis results, the rationality of design was confirmed.
