Tolerance Simulation in the Loop : Ansätze zur Verbesserung der Vorhersagegenauigkeit der Toleranzsimulation im Automobilbau durch Adaption an reale Fertigungsprozesse

Abstract

The dimensional accuracy in the body-in-white manufacturing process is analysed, basically confirming the simulation scope already in use. An enhanced prediction approach and a visualisation tool enable a precise and cost-efficient mapping of stamped parts deviation. As a result of joining operations parts can be deformed plastically, questioning the practical use of elastic tolerance simulation. A modified approach is presented based on the rigid body tolerance simulation.
