Durability analyses of a rubber to metal anti-vibration cone mount, subjected to a random type load signal by using damage models in finite element method

Abstract

Present study proposes a method for lifetime prediction of rubber-to-metal anti-vibration mounts, which can be divided into two approaches. Method is especially suitable for random type load signal, which is used for rubber mount validation tests. Method employs the cyclic tests until specimen failure and the Wohler diagrams. Random type load signal is used for strain based level crossing operation and after that, life time prediction can be done by using the inputs from Wohler diagrams and level crossing operations. Numerical approach and FEA approach only differ from each other in the determination of unit damages in making the life-time predictions.
