In order to investigate the dynamic characteristics of real structure, many dynamic engineer had been interested in modal test, however it is not easy to perform dynamic test of large structure because of many difficulties such as unsatisfied excitation force in global mode frequency range, measurement of dynamic force and so on. Therefore, new type vibration exciter with variable stiffness support system and dynamic force was developed to provide a improved experimental environment for a large and complex structure. The developed exciter improved from two viewpoint, dynamic performance and utility convenience, its characteristics was shown in this paper.

Recently the construction of stations under railway lines and railway sections passing through central area of cities are increasing, calling for an urgent establishment of countermeasures against railway vibration and its subsequent second-phase noise. Of technology developed up to now, the most efficient countermeasure is the floating slab track, a track system isolated from the sub-structure by springs. Unfortunately, however, the system design technology and technology for key components have not yet developed in Korea. As such, in this study, the analysis and design technology of floating slab track and its vibration isolator technology can be achieved. In preparation for future demands, it is expected to raise awareness for the need of technology self-support and to make a meaningful contribution to mitigating vibration and noise produced by the next-generation high-speed railway.

Of technology developed up to now, the most efficient countermeasure is the floating slab track, a track system isolated from the sub-structure by springs. Developed in this study, anti-vibration device for floating slab track (HLRM-High Load Rubber Mount) Haman station affiliated to the primary measurement was conducted in October 2012, one year after the second measurement after 2013 to be carried out in November and we want to change that. It is expected to raise awareness for the need of technology self-support and to make a meaningful contribution to mitigating vibration and noise produced by the next-generation high-speed railway.
