Synopsis

This report focuses on the optimization of a standard one-quarter inch (6.35 mm) wrench to minimize its mass by reducing the height and thickness in certain key locations through optimization and finite element analysis. The mathematical problem statement for the wrench design optimization is defined by the objective of finding the best design that satisfies all design requirements. The criterion for the best design is the objective function, which is the mass, and other design requirements include both equality constraints and inequality constraints. The report discusses the analysis of the structural system, material properties, objective function, loading, and inequality and equality constraints of the wrench. The report includes a detailed description of the wrench geometry and material properties used in the analysis. Additionally, the report presents the FEA results of different wrench designs with varying thicknesses and radii. The report concludes by summarizing the optimization process and discussing the benefits of optimizing the wrench design to minimize the mass and material usage, thereby producing a more efficient product.
