Rubber materials, which are widely used as anti-vibration products for vehicles, exhibit complex non-linear material behavior unlike general metal materials. Therefore, it is difficult to predict the fatigue life of rubber materials through finite element analysis(FEA), which is a virtual engineering technique. In particular, using the conventional SN diagram in fatigue life analysis, it is difficult to obtain reliable results because there are many variables affecting the level of the SN diagram. In this paper, fatigue life endurance analysis was performed using commercial software ABAQUS and FE-SAFE/RUBBER based on tear energy for rubber bushes for automobiles subjected to complex load conditions. Reliability was verified by comparing the results of the analysis with the test results. Also, in order to confirm the effect of strain crystallization on the durability of rubber bushings, the results obtained from the analysis and the test were compared. |
