Abstract
BACKGROUND: Topological optimization is widely used in aircraft construction and architecture, but is still of limited use in heavy machine building. At the same time, the production of parts, frames and other structures is often carried out by CNC (computer numerical control) plasma cutters. This makes it possible to produce flat parts of almost any complexity, including the use of topology optimization methods. Moreover, there is no need to use additive technologies to create three-dimensional structures. AIMS: The purpose of the study is to reduce the weight of the power components of the front end loader's working equipment without loss of rigidity and strength, as compared with traditional designs, and to explore the possibilities of topological optimization. MATERIALS AND METHODS: We used the DM-30 loader as the base machine. We converted its work equipment into a set of flat shape design volumes, to which the topological optimization methods of Autodesk Inventor Professional (AIP) were applied. As the structural steelwork of working equipment is subject to load in different directions during operation, we used a method of sequentially generating part forms for each design position and then synthesizing all forms into a single object. We determined the forces acting on the work equipment components by dynamically modeling the design positions for the base machine. It allows us to study the most operating situations. RESULTS: As a result, we reduced the weight of the front loader by 36%, while maintaining the same strength characteristics. CONCLUSIONS: The methodology proposed allows the use of simple topological optimization modules and produces up to 40% less metal-intensive spatial structures.
