Summary
In this paper, the focus is on the inverse problem regarding force localization in the case of a non punctual impact occurring on an elastic beam. Following the approach based on the reciprocity theorem to solve this problem, the impact location characteristics were determined using the particle swarm optimization algorithm. To eliminate numerical trouble due to the parasitic solutions resulting from the fixed boundary conditions, the fitness function was customized. Four different formulations of the fitness function were considered and their performance using three strain sensors were analyzed. This enabled the assessment of the best formulation to be used in the context of the impact force localization process based on the particle swarm optimization technique for this configuration of sensors.
