Numerical modeling and optimization of geometric parameters of a composite bracket

Abstract

Abstract The article presents the development and research results of the stress-strain state of a new composite bracket structural solution. The basic scheme of the invention and its application in hinged facade systems are described. The main feature of the developed design solution is the production of various shapes profiles made of aluminum alloys: a U-shaped profile with a wall thickness that varies along the length and an L-shaped uneven profile. Both parts of the bracket are made of aluminum alloys using extrusion method, which allows producing a profile of different shape on terms of area. The results of numerical modeling and selection of optimal geometric and physical-mechanical characteristics of the developed composite bracket in the software package are presented. The actual loads, impacts and operating conditions are taken into account. Based on the results of numerical studies, it is found out that the developed type of the bearing bracket meets the requirements of strength, rigidity and stability. The additional optimization allows reducing the weight of the bracket compared to the original model without significantly reducing the bearing capacity.
