Identification forces in contact wheel–rail
Culek B., Culek B. ml., Podruh J., Kolář M.
pages 57 - +5p., full text

In the paper is described an experimental procedure of identification of vertical Q wheel force and Y cross force. Checking of derailment resistance of railway vehicle is determined from proportion of cross Y and vertical Q force, which reacted between wheel and rail in the course of drive of vehicle. Till this time are developed principles of determination of Y and Q force through strain gauge measurement of disk wheel deformations. On wheels are placing two systems strain gauges. One system is for identification of Q force, second system is for identification Y force. Both systems are placing on wheels so, that has been minimized influence of Q force on measuring of Y force and counteraction of Y force on measuring of Q force.
