Constructive optimization by method of finite element analysis of hemp fibre processing equipment

Abstract

Finite element analysis (FEA) is a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. Finite element analysis shows whether a product resists under the working conditions, wears out, or works the way it was designed. Hemp fibre is a natural renewable material used in important areas of industry. The primary processing is performed on special equipment that ensures hemp fibre processing. In this study, the structural analysis module will be used for static analysis (resistance checking) and modal analysis (frequency analysis or calculation of a number of structure's own frequencies) for the important assemblies. The pressing and crushing rollers, their spindles and bearings and the frame (machine frame) of the hemp fibre processing equipment are analyzed and verified constructively and functionally. The results obtained are used in redesigning the equipment. Thus, it is expected that the new design of the hemp fibre processing equipment will have better performance in terms of metal consumption, energy efficiency and the quality of the obtained products. The equipment comprises a system with 8 pairs of processing rolls, and a vibrating system for separating the pieces from the remaining stems in fibre. The work is aimed at checking the dimensioning and the resistance to the efforts by the method of the finite element analysis (FEA) both for the construction of the rollers and the support frame.
