| Abstract |
The article discusses the development of a multi-degree model of a stand of a semi-natural
modeling stand under dynamic loading. The presents a technique for obtaining a three-layer model of
the stand, consisting of external load-bearing layers made of a five-layer composite material and a
filler layer between them, made of a foam-type material. The approximation of the stand by finite elements was carried out with the change of elements that are inadequate implemented in the finite element method: bearings, gear rims, reducers, by systems of rods identical to them by of rigidity.
The convergence of the calculation results was checked by thickening the finite element mesh. The
stress-strain state of the stand under dynamic loading was obtained and the natural frequencies of
oscillations were determined. The strength characteristics of the stand are determined depending on
the location of the fibers in the layer in a five-layer composite material. Theories of destruction are
used to calculate the strength characteristics of a five-layer composite material. The methods developed in the work are applicable to a wide class of robotic systems that are widely used in various fields of science and technology. |
