Design analysis of a machined part in a single step to replace a structural component assembled through non-destructive testing and FEA

摘要

In this study, a design analysis was performed through non-destructive test by rectangular rosette and uniaxial strain gages with FEA, between a structural aerospace assembled component of aluminium and a proposal part machined in one step with the same geometric characteristics. The analysis showed that the proposal part machined in one step has a trend to obtain less strain (0.5156mε@46.44N rectangular rosette strain gage, 0.4796 FEA) than the assembled component (0.7012mε@46.44N rectangular rosette strain gage, 0.7793 FEA). These findings indicate that the proposal part is a structural element with greater structural stiffness in comparison to the assembled component.
