✦ Synopsis
This work presents a new general approach in developing the force-prediction model. The two types of unknown forces dealt with in this study are the impact and the harmonic forces. Theoretical background of force-prediction model is extensively reviewed and categorised into two approaches, the direct and the optimisation approaches. Both approaches can also be further divided into the time-and the frequency-domain method. The structural response due to the unknown forces is then derived. The new approach, an optimisation approach, to predict the force magnitude and location simultaneously is developed for both time-and frequency-domain method. The implementation of the prediction model is also discussed. Special concerns about the applications to engineering problems are addressed.
