unitary piece of aluminum aerospace application (machined by removing material)
and an entity composed by several parts that have the same geometrical characteristics.
To verify the mechanical properties were tested by uniaxial strain gage and
FEA (Finite Element Analysis) with ANSYS. According to our results, the unitary
piece has a better structural behavior (structural stiffness) with a reduction
of the risk of failure and in manufacturing terms it presented a reduction of
required time for the production and manufacturing processes. The analysis showed
that in a constant load the unitary part presented less strain (0.0329 μ
with strain gage, 0.0321 μ with FEA) than the assembled part (0.0509 μ
with strain gage, 0.0599 μ with FEA). These results indicate that the single
piece works better in this operating condition, shown to be a structural element
with greater stiffness in comparison to its counterpart assembly. However, if
the work part was required not to be rigid to absorb vibrations, the assembled
would be better. Regarding to the reduction of time in the production and manufacturing
processes, the results showed 1.48 h for the unitary part and 3.31 h for the
assembled part, reaffirming the added benefit.]]>Anonymous,20142014Ashley, S.,19951995Boothroyd, G., P. Dewhurst and W.A. Knight,20113rd Edn.,Cristofolini, L. and M.
