Abstract

The methodology of damage detection through the observation of modal properties envisages continuous monitoring and belongs to the category of non-destructive methods. This work proposes a simple analysis to localize the damage inside a motorcycle component. For linear behaviour of the system under investigation, this methodology is focused on deviation of dynamical parameters (eingevalues and eigenvectors) due to the presence of damage (single o double) inside the component. Choosing a motorcycle carter is due to his particular complexity and to his location, during normal use it is working under high stress levels and little or large accidental hits could, if neglected, carry to an alteration of delicate equilibrium of motorcycle. The first step is to validate of Finite Element model and to simulate different single positions of damage. The second step was to introduce a damage in two different positions at the same time.
