| Description |
In the present scenario of aerospace sector,
structure weight is considered to be major factor in
deciding the performance, efficiency etc. One of the
potential major weight reduction contributor is the
structural airframe. Structure optimization which deals with
the structural weight reduction without compromising
strength is a complicated, time consuming and experience
based process.In this paper, optimisation of a critical
bracket of flying prototype aircraft engine mount is
demonstrated using a Finite Element(FE) based
optimisation software Altairoptistruct. The optimisation is
carried in two steps. Topology optimisation, which is
anelastic energy based optimisation to search for
anoptimum material distribution followed by a size
optimisationto get a final solution of the product. The
optimisation was carried with an objective of weight
reduction satisfying the strength requirements. As an
outcome of this exercise, the final product ready for
realisation is lighter in weight by around 20% compared to
the initial design.
