Simulation of Kinematic Pairs in the Calculation Mechanisms by Finite Element Method

摘要

Developed an original method, which allows us to apply the finite element method to analyze the stiffness and strength of planar and spatial lever mechanisms with kinematic pairs of arbitrary orientation in space. The idea of the method is that the basic equation of equilibrium of a system of finite elements is made and solved in the local coordinate systems of nodes. This allows to take into account the lack of connections in the kinematic pair in any direction. For the finite element modeling is used also a method of hard knots.
