Topology optimization of structures with manufacturing constraints in ANSYS Workbench 19.3

Abstract

The topology optimization analysis system of ANSYSWORKBENCH19.3 is widely used in structural design because it includes manufacturing constraints. However, the topology of the structure and the ease of manufacturing will also change depending on how these manufacturing constraints are set and used. This paper studies the methodology to obtain a more convenient topology on manufacturing while minimizing the mass of the structure by rationally setting the manufacturing constraints. An example of a structure is the base frame of a container used commonly. The effects of manufacturing constraints on the topology result of the structure are analyzed by simulation under different loading and constraint conditions and applying different manufacturing constraints. Based on this, we determined what manufacturing constraints should be defined to obtain the most practical topology. The paper will provide substantial support to engineers and researchers who are trying to solve practical engineering problems using engineering analysis applications.
