Abstract:
Quasi-static problems with respect to the stress-strain state and a class of
problems with respect to forced vibrations acting in plain and spatial nodes of a high-class
mechanism with elastic links are considered, taking into account the model of friction forces
in kinematic pairs under the action of vertical and horizontal concentrated forces in kinematic
pairs. The developed algorithms of solving quasi-static problems by the finite element method
for the entire system of the elastic mechanism with the friction force in kinematic pairs are
presented; the basic resolving equilibrium equations for the entire system are drawn up without and taking into account friction forces. The basic relations of the finite element method
for plain and spatial nodes of high-class elastic mechanisms with the friction force in kinematic pairs under dynamic loading are presented.
