METHOD AND DEVICE FOR ACQUIRING WHEEL WEIGHT MALDISTRIBUTION DEGREE, ROLLING STOCK, AND MAINTENANCE METHOD OF ROLLING STOCK AND RAILWAY

摘要

PROBLEM TO BE SOLVED: To provide a method and device for acquiring the wheel weight maldistribution degree of a wheel set having a maximum wheel weight maldistribution degree of wheel sets every truck in an optional measuring position for an optional truck in real time in traveling and also easily even in stopping. SOLUTION: A first coefficient as the average value of the wheel weight maldistribution degree of each wheel set 11 every truck 16 is determined on the basis of the internal pressure values of air springs 13 and 13, and a second coefficient as the maximum value of the dispersion width of the wheel weight maldistribution degree of each wheel set 11 is further determined, whereby the wheel weight maldistribution degree of the wheel set 11 having the maximum wheel weight maldistribution degree every truck 16 that is the index of derailment danger judgment can be determined on the basis of these coefficients.
