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