PROCÉDÉ ET INSTALLATION DE DÉTECTION DE L'ENDOMMAGEMENT D'UN BLOCHET
The invention relates to a method for detecting damage to a sleeper of a railway track. According to said method: the sleeper is excited (40, 72); then the vibratory response of the sleeper is measured; at least one first natural frequency (F1) of a first natural mode of the sleeper is determined on the basis of the measured vibratory response; and at least one level of damage of the sleeper is determined on the basis of at least said first natural frequency.
