In this paper, the vibration modal results were obtained by using the Block Lanczos modal analysis procedure in a commercially available FE software with the FE model shown in Fig. 3. The lowest 10 modal results were extracted and summarized in Table 1, and as a supplementary experimental investigation on an identical bogie frame structure [13,14] showed, any interactions between the natural vibration modes and external excitations are mostly in the lower frequency regime below 200 Hz (see Fig. 2). The measured modal results are given in Table 1 for comparison purposes. There are minor differences between the finite element method (FEM) modal results and test modal results. Owing to model of the finite element bogie frame (shown in Fig. 3), the detailed affiliated mass is neglected, which causes differences in the modal frequencies. For the same mode shape, an increase in natural frequency can be seen, which becomes more significant for higher modes. The mode shape results are compared in Fig. 4.
