Accurate prediction of contact stresses and wear of mechanical components in highly loaded machines is essential if reliable life prediction and maintenance plans are to be designed. It is a complex analysis requirement that cannot be performed using simplified methods
A three dimensional BEASY model was developed to simulate the contact and detailed slip and stresses present on the surfaces in contact under a cyclic fretting type load. The model produced accurate data for use in wear models and was validated against analytic test solutions as well as experimental test data.
A validated methodology has been developed which is capable of a high level of realism in the model both in the loading and the three dimensional geometry of the components. The output of the model provides data for wear type models and stress data can be used to investigate issues such as crack initiation and propagation.
