A safety evaluation on the loading and vibration test of freight car

화차 안전성 평가를 위한 차체 정하중시험 및 진동시험

This paper describes the result of carbody and vibration test for freight car. The purpose of the test is to evaluate an safety which carbody structure shall be considered fully sufficient rigidity so as to load a freight car under maximum load and operating condition on line track. The test carbody is constructed by RS korea co., LTD. in accordance with KNR specification. The test cases of the carbody is tested the vertical load and compressive load to verify the strength and stiffness. The vibration test is tested for analysis and evaluation of vibration, to allow for the fact that mechanical vibration in railway vehicles have specific characteristics.
