Establishing the Optimal Density of the Michell Truss Members

Abstract

Topology optimization is a dynamically developing area of industrial engineering. One of the optimization tasks is to create new part shapes, while maintaining the highest possible stiffness and reliability and minimizing weight. Thanks to computer technology and 3D printers, this path of development is becoming more and more topical. Two optimization conditions are often used in topology optimization. The first is to achieve the highest possible structure stiffness. The second is to reduce the total weight of the structure. These conditions do not have a direct effect on the number of elements in the resulting structure. This paper proposes a geometric method that modifies topological structures in terms of the number of truss elements but is not based on the optimization conditions. The method is based on natural patterns and further streamlines the optimization strategies used so far. The method’s efficiency is shown on an ideal Michell truss.

Component development using Topological Methods

“…To perform the topological optimization operation, it is advisable to create a new reference body model, which will be the modified geometry of the geometry of the reference part [8]- [11]. The modifications made to the model increased the overall volume of the part, but the functional elements remained unchanged.…”

An Analytical Method for Tensor Visualization in a Plane

“…In some mathematical applications, the tensor is defined based on the tensor product of vectors in a vector space. This definition leads to a tensor being an object without components, thus enabling the extension of the linear algebra concept to multilinear algebra [25,26].…”

“…Egy másik lehetőség azon térfogatok meghatározása, amelyekben nem lehet anyag, mert például valami más alkatrész mozog ott. Ha nincs kezdő munkadarab, akkor azt "térfogatrészként" kell megadni, amelyek a kész alkatrész részei lesznek [11][12] [13].…”
