Noise reduction and vibration control at high speed railway are required to improve the interior noise characteristics of aluminum car body system, which is used shinkansen train and express train. However, it becomes difficult to maintain the vibration control of one link mechanism between the car body and the car bogie. In this paper, to improve the damping performances of one link mechanism, we have proposed a new type noise reduction link mechanism using granular materials. Factors which affect the damping performances are examined through a numerical simulation study. The present noise reduction link mechanism is studied via examining damping performance with granular mass effect and friction effect. Finally, in the numerical simulation by using the discrete element method (DEM), new type noise reduction link mechanism is improved by max. 4.6dB in comparison with the conventional one.
