Method of determining the forces in the wheel-rail contact in rail vehicles

摘要

Method of determining the forces at the wheel-rail contact on rail vehicles, comprising placing strain gauges (3) forming two Wheatstone bridges on positions of the web of the wheel (1), providing strain signals veil according to radial direction, so that two measurement channels that provide two signals depending on the angular position of the wheel (1) relative to the wheel-rail contact, with the following steps for determining the positions of the strain gages are obtained (3): # - Deduction of a function that provides the value of strain # - Construction of a function that theoretically provides the value of output channel bridges # - Definition of objective function for an optimization problem #... - Selection on two pairs of opposing two sets of quadrant points. # - Obtaining positions gages (3) optimization mat emática.
