A study on the testing methods of air spring for railway rolling stock

철도차량용 공기스프링 시험방법 규격안에 대한 연구

Air spring for railway rolling stock is a part of secondary suspension system, which is supporting load, damping vibration. Recently, air springs are actively applied to railway rolling stock to substitute the coil spring by upgrading the manufacturing skill. This study is started to develop draft for the testing methods of air spring for railway rolling stock. We have tested several items on testing methods to guarantee the performance of air spring. Thus, we have developed the test draft for air spring.
