Double pendulum contact problem - Diploma thesis

Popis výsledku v původním jazyce

The thesis concerns contact problem focused on biomechanical systems modelled by multi-body approach. The example is modelling impact between human body and infrastructure. The work firstly presents algorithms for collision detection and for calculationof minimum distance, respectively. In the thesis the analytical method using tangential plain perpendicular to initial one is analysed. The Hertz, the spring-dashpot and the nonlinear damping contact force models are applied in approximation of the contact force, generated during the impact of bodies. Later on, numerical optimization method is put upon bouncing ball example. The difference between initial experiment and simulation curves is desirable to be minimise. Purpose of optimization is to find the most corresponding results of simulation to an original experiment. As consequence of these, adequate parameters of all the three contact force models are calculated. Derivation of double pendulum equation of motion is performed using L
