In order to improve the safety of railway vehicles, it is vital to prevent derailments and secondary accidents by detecting troubles of vehicles. Described here is our research on the derailment detection by sensing abnormal acceleration or angular velocity on every rigid body of railway vehicles, and on a derailment detecting method and apparatus for preventing secondary accidents. However, because of complex root causes of derailment, it is difficult to detect their signs before the wheel climbs upon the rail or even leave the rail. Therefore, a 1/10-scale model of railway vehicles including one car body and two bogies as well as a device that can simulate various climb derailments for a chosen wheel are designed and invented. Based on the twenty-four cases of experimental derailment tests, an algorithm for detecting foretastes of derailment beforehand is proposed, and it is verified that abnormality can be detected before the wheel climbs upon the rail.
