COMPARISON AND ANALYSIS THE EFFECT OF VIBRATION CONTROL SLEEPER PAD ON GWE_MOK ELEVATED RAILWAY BRIDGE IN JEOLLA LINE

초록

Any noise and vibration from railway line is carefully considered most important factor to estimate railway safety and passenger comfort. Even though railway has recognized the very friendly environmental transportation than motors it still has heavy environmental problem such as high nose level and vibration from railway line. "There are few reasons for vibration and noise from railway line. In order to reduce vibration levels, its source and routes must be prevented. The reduction of vehicle dynamic load can be best solution dealing with this matter. Diminution of sleeper spring constant is also considered another solution. In this paper, the effect of vibration reduction with vibration absorber is investigated on Jeolla line (south-west line of South Korea). The results are compared and estimated based on different measuring factors."
