The structural synthesis of planar mechanisms with dyads is presented. A classification of dyads is elaborated. New planar mechanisms are constructed using this classification of dyads. The trajectories for different mechanisms are studied. The advantage lies in the classification of the kinematic chains. The solution of the whole system can then be obtained by composing partial solutions.
The impact between rigid bodies with friction is studied. The rolling friction moment and the coefficient of rolling friction are introduced, and an improved mathematical model of impact with friction is presented. The influence of the moment of rolling friction on the energy dissipated by friction during the impact is analyzed. For a simple pendulum, using the energetic coefficient of restitution, more energy is dissipated for larger values of the coefficient of kinetic friction and contact radius, and for smaller values of the length of the beam.
