철도차량 실물충돌시험설비를 이용한 탱크컨테이너 충격시험 기법 연구

초록

The impact test criteria for a tank container requires field tests as designated by ISO1496-3 standard. Full-scale crash test facilities are indispensible for the impact test of a tank container. KRRI(Korea Railroad Research Institute) recently established the full-scale crash test facilities which can afford to perform the field test according to ISO standard. KRRI has performed several impact tests of 20ft/40ft tank containers made by U&S Co. and Samsung Heavy Industries Co. The key aspect for the test is the SRS(Shock Response Spectrum) criteria. SRS criteria require the impact characteristics to be certain amount of accelerational measure. For the reason, impact testing setup needs adjustable shock absorbers and appropriate impact speed. The impact test has been performed in the straight testing track and stationary impact barrier. Tank container prototypes successfully passed the SRS criteria generated by combination of side buffers for railway vehicles.
