Dynamic model of a system of elastically coupled particles for topological optimization of composite material products. Journal of Instrument Engineering

Abstract

The object of research is composite materials, the main advantages of which include low weight of the structure and high resistance to mechanical and thermal loads. In order to predict possible loads on composite structures and take these data into account at the initial stage of parts development, computer modeling of the processes associated with them is required. A grid-less method for optimizing products made of composite materials based on elastically bonded meta-particles is proposed. The results of optimization calculations of dimensions for a test beam under the action of a static deflection load are obtained. The software implementation is carried out in JavaScript without third-party libraries. The weight reduction comprises 25% of the original model. Verification of the optimized geometry is performed under similar conditions of mechanical loading in the Ansys Student package. The developed prototype can be used to determine the possible percentage of weight reduction of a composite structure.
