Rubber to metal anti-vibration cone mounts is used in a wide range of industrial applications, which have different loading characteristics. These kinds of cone mounts are produced mostly with standard dimensions and typical rubber compounds. In system development activities, effective usage of cone mounts can be improved, when its’ long term behaviors like durability can be technically defined, besides its’ static and dynamic characteristics. The present study includes a durability determination study on a cone mount, which has standard dimension and rubber material by using rubber damage models in finite element method. A commercial FEA code MSC Marc is used for finite element analysis. Modeled damage behavior of cone mount is verified on a hydraulic dynamic test bench, which is able to run random road load data. Loading profile is specially defined as “Random type load signal”, to create a wide usage platform for proposed method on system development activities. Damage model parameters, which are calculated as a result of data acquisition activities on standard tensile and compression rubber test specimens, is used to setup and verify the FEA models. In the present study, different rubber damage models are used and compared to show their precision on results. The strain-based level crossing is applied on random type load signal and damage models are set, according to repetition and strain level of the signal. Verification performance and effectiveness of the proposed method is reported in a comparison between FEA results and physical test results for durability behavior of same cone mount.
