극한 온도에서의 철도차량용 현가부품의 특성연구

A Study on the Characteristics of the Suspension Components of Rolling Stocks in the Very low Temperature

This study is a preview of characteristics of (1st/2nd) rubber suspension parts in low temperature, it will be researched before Trans Korean Railway and continental railway network connection. Rubber material characteristics are different to steel materials. Behavior of rubber material shows large deformation in hyper-elastic region. Moreover, added dashpot and low temperature condition shows various non-linear characteristics.
