Nonlinear finite element calculations in problems of strength of lifting-transport machines

Abstract

The main approaches to lifting-transport machines simulation by finite elements method are under consideretion in this article. Contains general provisions for performing nonlinear finite element calculations of load-bearing metal structures of handling machines. The algorithms of constructing stiffness matrices of nonlinear finite element and iterative algo-rithms for the numerical integration of the equations are shown. These are results of nonlinear simulation of the test objects and the overhead conveyor belt.
