We performed acoustic-structural coupled analysis and verification experiment using full-scale testing sample in order to verify adaptability of acoustic-structural coupled analysis for hammering test simulation of slab track: railway track for shinkansen et al. From this study, it is found that this analysis method is applicable to simulate frequency response characteristic and maximum sound pressure for slab track.
