摘要：

When the air springs on a railway vehicle go flat, wheel load is decreased by track irregularity. In order to examine the running safety of the railway vehicle under the air spring deflation, running tests were carried out, and various data such as wheel load, lateral force, force acting on the air spring and the amount of climbing of the wheel were obtained. Furthermore, we constructed a numerical simulation model of a railway vehicle in consideration of an air spring deflation, and its validity was confirmed through the comparison with the test results. © 2019 Ken-yusha Inc..
