Design Study for a New Spanner

A replacement for the original F-spanner is designed using computer-aided engineering (CAE) and the Taguchi method. In the design process, the L-9(3(4)) orthogonal table was used for parameter design. Four control factors are used: outer diameter, bend radius, angle, and connected fillet. Each factor is set to three levels with numerical analysis using ANSYS software. After performing an optimization analysis for the combination parameters, the prototype is created by rapid-prototyping (RP) and is found to improve operational safety in a piping system.
