DIMENSIONAL AND GEOMETRICAL OPTIMIZATION OF STRUCTURES AND MATERIALS FOR CURVED OR MOLDED CHAIR FURNITURE

Abstract

Based on the finite element method from COSMOSXpress package, Solid Works, the study analyses the possiblity for dimensional and geometrical optimization of sitting furniture structures, made of wood or composite materials based on wood. Concentrated or distributed load is applied to structures, according to the real load incurred at structures in use. As a result of test analysis, the structures can be dimensionally optimized. By observing the stress zones and maximum deformation zones, the designer can intervene on the 3D structures remodel. Another important aspect of the study is to enlarge the Solid Works database, by introducing new solid and composite wood materials. The finite element analysis process for the new materials requires the program library to have the following parameters: Elastic modulus, Poisson’s ration, Shear modulus, Mass density and Yield strength.
