A Review of the Indirect Calculation of Excitation Forces from Measured Structural Response Data

Using discrete structural models it is possible to predict accurately the response to any form of excitation providing that the behaviour remains linear and damping mechanisms approximate to specific, mathematically describable, forms. Theoretically this process should be reversible so that excitations can be identified and quantified from masured responses. However, in practice this process is often unreliable. This article reviews the work that has been done on force prediction and highlights those areas that require further research.
