Sometimes the best method for solving a dynamics problem is to gather data from both experiments and simulations. This has always been done but traditionally these have been separate disciplines. There is an initiative known as Fusion of Test and Analysis (FTA) which coordinates these activities. The objective of this workshop was to explain and show how fusion is applied.
This initiative is already operating in some high tech industries and has also been adopted by some specialist dynamics organisations. It has significant advantages in reducing uncertainty and is often faster, cheaper and simpler than using simulation or test alone. It is being adopted as a way forward for solving dynamics problems. In particular, one example of a new test method for qualification testing gives order-of-magnitude enhancements to the technical performance of a test, with the traditional over-tests and under-tests virtually eliminated. Typically, this can be achieved with a 3 times reduction in test running costs and a 6 times reduction in test infrastructure cost.
