Energetic transition in automotive industry leads to production of new parts such as battery trays. These parts present machining challenges linked to their vibration. It was shown that dynamic model accuracy is highly conditioned by fixture modeling. In the present work a clamping modeling approach for machining simulation is presented. Updating methodology of fixture stiffness and damping, based on dynamic reduction, is detailed. It allows to assess the influence of fixture on part dynamic behaviour in machining. Numerical predictions of ma chined surface geometry are compared to experiments on a battery tray part.
