A new method has been developed to continuously measure lateral and vertical forces between a locomotive wheel and rail. The technique utilizes strain gages applied to a typical locomotive wheel plate to generate sinusoidal waveforms which are electronically combined to provide continuous signals proportional to the lateral and vertical components of the net wheel loading. Two wheel axle sets and signal processors have been assembled incorporating this technique. These wheelsets have been used in extensive field testing of locomotives and the results have shown that crosstalk between lateral and vertical force signals, temperature effects, and lateral wheel orientation on the rail effects have been effectively minimized. This paper describes the continuous force measurement concept and instrumentation details. The use of these wheelsets provides researchers with a valuable tool for furthering the study of the dynamics of wheel and rail interaction.
