The control of structural vibration in cars, aeroplanes, ships, etc., is of great importance in achieving low noise targets. Currently, such control is effected using viscoelastic coating materials although much current research is concerned with active, anti-noise based control measures. This paper is concerned with a third approach: that of using advanced(More)
Engineering design studies can often be cast in terms of optimization problems. However, for such an approach to be worthwhile, designers must be content that the optimization techniques employed are fast, accurate and robust. This paper describes recent studies of convergence and robustness problems found when applying genetic algorithms (GAS) to the(More)
Over the last decade, Evolutionary Algorithms (EAs) have emerged as a powerful paradigm for global optimization of multimodal functions. More recently , there has been significant interest in applying EAs to engineering design problems. However, in many complex engineering design problems where high-fidelity analysis models are used, each function(More)
This paper presents an approach for combining approximation models with genetic algorithm-based design optimization procedures. An important objective here is to develop an approach which empirically ensures that the GA converges asymptotically to the optima of the original problem using a limited number of exact analysis. It is shown that this problem may(More)
This paper presents a study on parameterisation methods for airfoil shape optimisation within a CAD-based design optimisation framework. The objective of the paper is to study the effect of different methods on airfoil shape optimisation when using computational fluid dynamics (CFD). Parameterisation of geometry is one of the essential requirements in shape(More)
Autonomous vehicles are energy poor and should be designed to minimise the power required to propel them throughout their mission. The University of Southampton's School of Engineering Sciences is actively involved in the development of improved designs for aerial and maritime autonomous vehicles. The ability to adapt or 'morph' their shape in-flight offers(More)
The traditional approach to improving the lethality of a missile has been to concentrate efforts in the guidance and control systems to improve accuracy and agility. In this paper, we consider how optimizing the endgame, the final few milliseconds before detonation, can yield improvements in overall lethality. As there is likely to be uncertainty in both(More)
