Ergometer, e.g. for training sports cyclists, - measures deformations of pedals, handlebars and seat stem independently in orthogonal directions

摘要

The ergometer separately measures all four possible elastic deformations which can occur in a pedal lever, i.e. bending in the rotation direction, bending perpendicular to this direction, extension along the lever and torsion about the lever. The direction and amplitude of the force applied by the rider to the pedal are derived using Hook's equation or elasticity theory. The force is measured at many different angular positions of the pedal. One revolution is divided into a large number of small angle intervals, between which the force is quantised and the time recorded. The forces acting on the steering mechanism and saddle are determined from the elastic deformations of the handlebar and saddle stem respectively in three orthogonal directions. USE/ADVANTAGE - For training with sports equipment, e.g. cycle. Enables optimal motions to be determined and taught to sportsman.
