Sensor optimization for impact detection – A Bayesian approach

A Bayesian optimization strategy resulting in optimal sensor locations for impact localization under operational conditions is developed and presented. The impact detection methodology is based on developing meta-models utilizing artificial neural network (ANN) through the recorded sensor signals generated by various impact events. The novelty of the proposed method is to include the probability of one or more sensors failing under operation as well as non-uniform probability of impact occurrence in the structure. Finally, the proposed optimization algorithm is applied to a composite stiffened panel.
