Bushings and rubber springs in service are often loaded by stochastic and dynamic forces or displacements. These loads at sufficient level and frequency can damage rubber parts. An approach is proposed in which the distribution of the damage in a rubber part resulting from a stochastic multiaxial signal can be calculated. The stresses and strains in the material resulting from the load were calculated by FEM. Interpolations are used to transform the load-signal into the internal stress or strain histories. A Woehler approach and the linear cumulative damage rule from Miner are used. Basing on Woehler-curves or Haigh-diagrams the damage of rubber parts can be calculated for real dynamic loads.
