A re-design based on a fast prototype dynamic response analysis for point of sale consumer station was completed. The benefits of fast prototyping is to validate many aspects of a new design, but the dynamic and structural response of the fast prototype does not indicate that of the final production version of the design. This project involved dynamic measurements of the fast prototype design and correlation to an analytical model of a spring loaded door opening. The dynamic response of the final production version, with changes, was predicted and a custom coil spring design/specification was completed to provide a desirable dynamic response. Additional analysis support was completed with a nonlinear finite element analysis for the snap together design. The calculation determine the peak force experienced for product drop test where the peak force had to cause disassembly without breaking.
