Abstract
A dynamic friction measurement apparatus includes a load cell, accelerometer, and a computational device for determining the coefficient of friction corrected for inertial forces which otherwise cause an error in the calculation. The calculation device has the functions of simultaneously receiving the signals, conditioning the signals, creating output in digital or analog electrical signals, and storing or providing a value for the coefficient of friction from the dynamic measurements. A method for detecting and processing the coefficient of friction during dynamic condition is also provided.
