提高铁道车辆HILS系统试验频率的方法研究

Research on the Method to Expand the Frequency Range of HILS System on Rolling Stock

过去的铁道车辆HILS系统(硬件在环仿真,即半实物半虚拟仿真)的试验频率较低,无法重现车体的弹性振动。本文介绍了提高试验设备频率范围的方法,并对所建立的数值模型进行了试验验证。

The test frequency of HILS system （Hardware in the Loop Simulation, i. e., semi-physical virtual） on rolling stock in the past is fairly low, and cannot reproduce the elastic vibration of carbody. In this paper, the method to expand the frequency range of test equipment is described, and the numerical model established is verified by testing.
