Challenge: Lightweighting a Mounting bracket for Material Efficiency
Mounting brackets are ubiquitous engineering components. However, over-designed brackets use excessive material, increasing weight and cost. This project addressed the challenge of reducing material usage and weight in a mounting bracket while maintaining its structural integrity under load, utilizing the powerful technique of Topology Optimization.
Solution: Topology Optimization and FEA Validation in SolidWorks Simulation
To achieve a lightweight yet robust design, I employed a two-pronged approach using SolidWorks Simulation:
Topology Optimization Study: I utilized SolidWorks Simulation's Topology Study tool to intelligently remove material from non-critical areas of the initial bracket design. This was achieved by defining:
• Load and fixture conditions representative of the bracket's intended application.
• Design space – the initial volume from which material could be removed.
• Optimization goal – to minimize mass while maintaining a target factor of safety or maximum stress limit.
• Manufacturing constraints (symmetry, preserved regions)
Finite Element Analysis (FEA) Validation: After obtaining the topology optimized shape, I performed a detailed Static Stress Analysis in SolidWorks Simulation on both the original bracket design and the topology optimized design. This FEA validation served to:
• Verify the structural integrity of both designs under the applied load.
• Compare stress distribution and deformation between the original and optimized brackets.
• Confirm that the topology optimized bracket achieved significant weight reduction without compromising structural performance.
Key Deliverables & Visualizations:
This project delivered a clear visual story of design optimization and structural validation through a series of images showcasing different stages of the process:
