Keywords:
Layered material, agricultural machines, case of the machine, finite elements, eigenmodes.Abstract
Layered materials are used as cases of some types of agricultural machines and devices. They have an advantage in the transmission and suppression of some types of vibrations in the process of operation of those machines. In this paper a layered beam type structure is investigated. It is assumed that layers are of two types: 1) of the beam type and 2) of the elastic body type. Usually, the lower and upper layers are of beam type and the internal layer is of elastic body type. Finite element models of the layer of beam type as well as of the layer of elastic body type are developed and described in the paper. Based on them finite element of a layered beam is obtained. Eigenmodes of the beam of this type are calculated and investigated. The presented results are applicable in the process of design of elements of agricultural machines and other engineering devices.
