Topology Optimization of Finite Periodic Structures with Compliance and Frequency Criteria

Periodic structures effectively address challenges in manufacturing, transportation, and installation of large-scale systems by streamlining processes and enhancing transport, replacement, and assembly efficiency. This paper introduces a topology optimization method specifically for cantilever beam structures, to minimize structural flexibility and optimize frequency by determining the optimal material distribution under given loads and constraints. The study explores continuum periodic structures, examining the effects of material properties, optimization parameters, and boundary conditions on the outcomes. Various aspects of periodic optimization design, such as structural configuration, connections, and layout, are also investigated. Through the application of topology optimization using SolidWorks and Ansys, the experimental results validate the method’s effectiveness in enhancing structural performance and material utilization. This research presents a systematic approach and highlights the practical potential of designing periodic structures.
