Running safety estimation of Korean style high speed railway vehicle

초록

For the safety of railway, it should be evaluated for the running safety by measuring the derailment coefficient[1,2]. Although railway has run the fixed and maintained rail, some of railway is derailed. This report shows the results that performed the static load test, wheelset manufacturing for test, main line running test on the basis of the derailment theory and experience. It is executed main line test into more than 200km/h for estimating the running safety of korean style high speed railway vehicle. As the test results, could confirm the running safety of high speed railway vehicle from the results of the wheel unloading, lateral force, derailment coefficient etc. Derailment coefficient was less than 0.6, and lateral force allowance limit and wheel load reduction ratio were enough safe.
