Abstract
In the present work finite element analysis, FEA, ATILA((R)) models were generated to analyse the frequency behaviour of cymbals as a function of the bonding layer. The experimental frequency responses were correlated with predicted values. The epoxy thickness variation, the presence of epoxy meniscus or lacks of adhesive contribute to the frequency dispersion of the vibration modes. A statistical rupture test was developed where the cymbals were axially loaded in a universal mechanical test machine and monitored with an electrometer. The debonding was revealed by the generated charge versus the applied force. The adequate relationships between bonding nature, frequency response and debonding were established and shown that the asymmetries are the main parameter to control in the cymbal assembly.
