Simulation models of test equipment for measuring transient friction in a rolling and sliding contact

• This paper investigates how a model for boundary lubricated rolling and sliding contacts can be integrated in a dynamic rigid body model of a mechanical system in order to improve the accuracy of simulations of system behavior. The system modeled is test equipment for the measurement of transient friction in rolling sliding contact between two discs. Two different models of the system were constructed: one neglecting the rolling and sliding contact and the other integrating it in the system model. In the integrated contact model, the pressure distribution was computed using an elastic foundation model. A brush model was used for the friction calculation. Simulations were performed with both models and validated by experiments. The results show that the contact needs to be included in the model in order to capture the behavior of the system. Since the contact model used can handle both microslip and gross slip, it is applicable to a wide range of contact conditions.
