Parametric Topology Optimization of a Cylinder Mounting Bracket Using PTC Creo

Resumen

opology optimization is an emerging design technique for producing extremely lightweight, highly efficient structural components without compromising structural integrity. In the current investigation, the topology of a circular mounting bracket is optimized using the integrated structural optimization capabilities of PTC Creo Parametric software. The objective is to minimize the structure's weight without compromising its strength and rigidity. From an initial weight of 1.189 kg, the design was optimized through six phases to achieve the required weights of 70%, 50%, 35%, 25%, 20%, and 17.5%. The actual weight reductions were 71.2%, 52.3%, 37.2%, 27.1%, 22%, and 19.5%. As weight decreased, relative strength increased substantially, reaching a maximum of 100.833 MPa/kg. After analyzing failure modes and strength characteristics, particularly bending failures, the 20% weight-retention design, weighing 0.261 kg (22% of the original weight), was found to be optimal. The results of the study demonstrate that it is possible to create lightweight, high-strength mounting brackets suitable for industrial and automotive applications using parametric topology optimization in PTC Creo.
