Structure Optimization of Passive Damped Composite Beam

Popis výsledku v původním jazyce

Composites are already widely used in the aircraft industry and they are gradually being increasingly used in other industrial fields. Their inherent superior mechanical properties can be enhanced by the addition of totally different materials into the structure, creating 'hybrid composites'. Improved damping while retaining the original stiffness can be obtained by using any viscoelastic materials. Such treatment is part of passive damping control. This paper deals with optimization of simple structures consisting of carbon fiber reinforced polymer (CFRP) and cork composition in layered form. The goal was to determine the optimum number and location of damping cork layers to achieve the highest bending stiffness and damping of a simple cantilevered beam with a square tube cross-section. Numerical models were created using finite element method (FEM) software MSC Marc. For the purpose of optimization, the Pareto front algorithm was used with the help of optiSlang software.
