Computer Aided Liner Optimization for Broadband Noise

trevor — Wed, 02 Jul 2008 12:57:00 GMT

Dezineforce optimisation is applied to understanding the benefits of different configurations of sound absorbent acoustic lining in aircraft turbofan engine intake and bypass ducts. Noise emissions are 30% lower than with a uniform liner.

Speed at sea - ship design

trevor — Thu, 29 May 2008 12:03:00 GMT

DezineForce optimisation is applied to the design of low resistance ship hull forms. The final design has a resistance that is nearly halved compared to the starting point.

Reducing weight of a gas turbine tail bearing housing component

trevor — Thu, 29 May 2008 12:01:00 GMT

Dezineforce optimisation is applied to reducing the weight of a gas turbine Tail Bearing Housing component, without exceeding given stress or displacement constraints at any location on the structure. The final structure is 40% lighter than the original design.

Turbine firtree root design optimisation

trevor — Thu, 29 May 2008 12:00:00 GMT

Dezineforce optimisation is applied to the optimisation of a turbine blade firtree root against a number of geometric and mechanical constraints. The peak notch stress is minimised simultaneously with minimisation of the frontal area and root size.

Vibrations in space - satellite truss design

trevor — Thu, 29 May 2008 11:59:00 GMT

Dezineforce optimisation is applied to the design of satellite trusses with enhanced vibration isolation characteristics. The designs show significant improvements in vibration control without weight penalties.

Topology optimisation of load-bearing structures

trevor — Thu, 29 May 2008 11:58:00 GMT

Topologically-optimised designs of load-bearing links and support beams demonstrate much greater material saving than possible with pure shape optimisation, and dezineforce optimisation makes this possible.

Design of experiments for automated selection of skin-stiffening methods for aircraft wings

trevor — Thu, 29 May 2008 11:54:00 GMT

The experiments are designed such as to enable selection of the appropriate stiffening method from the very large number of possible combinations - efficiently, and such as to allow the designer to visually understand the effect of different variable values.
