Train Crash Test Facilities and Application

초록

Train crash test facilities were established by Korea Railroad Research Institute (KRRI) recently as the first full-scale crash test site in Asian countries. Korea has established the train crashworthiness guideline in 2007. The guideline includes three steps of crashworthiness design and evaluation. The full-scale crash test facilities are essential to first two steps of crashworthiness design and evaluation. The crash test facilities consist of a testing track, measurement devices and test cars. This paper includes detailed history of constructed facilities, test procedure and applications. The reliability of the measurand was first figured out for the load, displacement, acceleration and energy absorption by evaluating the uncertainty in measurement on the basis of the ISO guide (GUM: Guideline to the expression of Uncertainty in Measurement). The crash or impact test for railway vehicles can be categorized as single item tests, module tests and crash structure test. KRRI has conducted several dozens of crash tests and plans to introduce the typical crash test procedure and results. The full-scale train crash test facilities of KRRI can provide a differentiated on-demand crash test service to global customers.
