Modelling Friction and Impact More Accurately

Nowadays, everything is designed on a computer before being manufactured, including parts of an airplane, jet engine, and gearbox. Such components though can suffer friction and impacts that cannot be properly modelled on computers, making prototypes a necessity for safety. Researchers at the University of Bristol want to change that and have crafted a new modelling technique that can accurately predict the effect of those forces, without a prototype.

Algorithms to predict the damage a device will incur as a result of friction or impacts have been developed before, but have not been very accurate. In part this is because some of those behaviors are so nonlinear that they create great uncertainty in engineering systems. The new Bristol model however is able to better describe what happens as it takes effects into account previous models had not.

This model could have a number of impacts, including greatly reducing the cost of engineering systems that endure friction and impact. It could also affect the modelling of non-smooth systems.
