Abstract
The running stability assessment Method of railway vehicles was performed using small-scaled derailment simulator based on the similarity rule of predicting the dynamic behavior of railway vehicles. 1/5 scale power car bogie of a high speed train was designed and manufactured. And a running stability test was performed on each 1/5 scale bogie using a Small-Scaled Derailment Simulator and the running stability characteristics associated with the critical speed of the 1/5 scale bogie was ascertained. To carry out research through comparison with and verification of the running stability test results of the 1/5 scale bogie its running stability was performed by means of dynamic analysis programs.
