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。
With the rapid development of China’s high-speed railway, research on high-speed and heavy-load freight trains has been carried out in an all-round way and the research on full-size trucks will play an increasingly important role. In the full-scale test study, the basic design of the truck test bed is crucial to the normal operation of the entire test bed and data acquisition. In this paper, the dynamic analysis of the test bed foundation is carried out by using the lumped parameter model, and the modal analysis is carried out by MIDAS software to verify the rationality of the designed basic system.
