摘要

The invention is directed to a derailment detecting method for rolling stock (1), which is applied to rolling stock having a truck (3) which comprises wheels (5) rolling on rails (4), and spring rigging (6), and a carbody (2) to which said truck is attached, said derailment detecting method for rolling stock comprising:a step of detecting vertical acceleration at said carbody (2) above said spring rigging (6) during running of said rolling stock on said rails (4);a step of calculating a vertical displacement amount by double integral of said vertical acceleration every evaluating time, said evaluating time being defined as a time period from a start of descent of said carbody to arrival at half a heighth2 of said rails, in a free fall of one axle of said wheels (5) by a distance equal to the height (h) of said rails; anda step of determining that said rolling stock (1) is derailed, in the case that said vertical displacement amount is negative and an absolute value thereof is not less than a predetermined reference value.
