Computer models now under development could enhance the design of sports equipment to help people of all abilities realise their sporting potential.
The models, more sophisticated and more specialised than others previously used in sports equipment design, produce unprecedentedly realistic simulations of how potential ball designs, for instance, will actually behave when in use.
This data can then be harnessed by sports equipment design teams to ensure that the final products they develop behave (e.g. bounce and spin) as required and, above all, with more consistency than ever before. This is vital if sportsmen and women are to optimise their skills, apply them with confidence and maximise their achievement.
The capabilities of these new computer models, which are being developed at Loughborough University by a team from the Sports Technology Research Group, will be described at this year's BA Festival of Science in York.
"The UK is at the forefront of sports-related engineering," says Dr Andy Harland, who leads the team and will deliver the presentation on 13th September. "Our computer models can provide invaluable technical input to the sports equipment design process. For example, by enabling the real-world behaviour of different design options to be simulated with extreme accuracy, they can reduce the need to manufacture expensive prototypes and cut the time required to get improved equipment from the drawing-board to the shops."
The basis of the models is provided by commercially available, industry-leading Abaqus software. The team take this software and then, by developing and adding complex algorithms*, enhance its ability to simulate mathematically the exact characteristics of a particular piece of sports equipment, of different playing surfaces and so on. The model can then show exactly what will happen when a ball, for instance, has a specified amount of force or spin applied to it, and how it will bounce and roll.
The underlying expertise has been developed with funding from the Engineering and Physical Sciences Research Council (EPSRC). Further funding targeted at specific objectives has been provided by adidas, the global sports equipment manufacturer. Key input has already been made to the design of the adidas +Teamgeist football used in last year's World Cup in Germany. As well as other football projects, Andy's team are currently working on models that will aid the design of next-generation running shoes which reduce the risk of injury.
The capabilities being developed could also allow designers to tune sports equipment more closely to the needs of the user, leading to increased participation in sport and therefore important health benefits across the population.
"There's plenty of anecdotal evidence that children and some adults are deterred from taking part in sport by ill fitting or badly designed equipment," Andy Harland comments. "It's ironic that a largely sedentary activity like developing computer models can make a real contribution to the quality of sporting performance and the enjoyment millions of people derive from physical activity."
EPSRC funding has been provided under the auspices of Loughborough University's Innovative Manufacturing Research Centre (IMRC), a 5-year initiative which began in 2006 and is receiving EPSRC funding of nearly £18M. The overall aim of the IMRC is to undertake a wide variety of work in the fields of manufacturing, construction and product design.
To develop computer models of the necessary sophistication, Andy and his team are harnessing a wide range of skills available at Loughborough University, including mechanical engineering, computer science, electronics, civil engineering and even psychology (the issue of how users perceive sports equipment is a hugely important one).
Developed by Simulia, Abaqus is a suite of non-linear finite element analysis (FEA) computer programmes designed for use in tackling a wide range of mechanical, structural, civil, biomedical and other engineering challenges.
