Methodology for calculating the stress-strain state of robotic system made of composite materials

摘要

Abstract The methodology for calculating the stress-strain state of robotic systems made of composite material under dynamic load is considered. The problem is solved by the finite element method. Formulas for determining the reduced stiffness of a multilayer composite material are given depending on the location of the base of the composite in layers, as well as in three-layer structures consisting of external bearing layers and a layer of aggregate between them. The method of placing the base layers of a composite material in the structure under study along the lines of maximum stress is considered. Particular attention is paid to the accounting of gearboxes, gears and support bearings in robotic systems. The results obtained in relation to the multi-stage dynamic stand, made of composite material.
