Modeling of the Constrain of the Foot with the Bicycle Pedal While Driving with a Constant Cadence

摘要

This work was undertaken to create models and conduct numerical studies on them with different foot-pedal constrain while rotating the crank of the bicycle. The movement in individual joints was induced based on the characteristics obtained by the inverse kinematics task. In the studies, the load characteristics of the main active joints: hip and knee were created, based on the displacement characteristics obtained through a direct kinematics task. Test conditions were established according to cycling with a standard cadence of 90 rpm. Numerical experiment was conducted in the ADAMS environment, on the created spatial model that takes into account human's lower and upper limbs. The results obtained from the numerical studies form the basis for the development of the full biomechanical model of the human-bicycle system and represent an introduction to a more complex dynamic analysis and optimization related to this system.
