Abstract
The parameters of high speed trailer wheel were identified by modal test using hammering method. Based on the actual measured dynamic stress data, the frequency spectrum was obtained and the transfer function was analyzed. Compared the results of the frequency spectrum analysis and the modal parameters of the wheel set, the primary frequency in frequency analysis and all the frequencies with higher amplitude in the transfer function were far from the natural frequency of the wheel set. The results show that the train is safe running on high speed line.
