摘要: Interaction, in real time, between a designer and virtual prototype is promising way to optimize the parts design mechanical industries. These interactions can induce deformation of some flexible prototype. The analysis time nonlinear model by finite element method (FEM) impossible. Our approach based on two phases: 1-some load cases, characteristic possible handlings, are precalculated; 2-results this campaign interpolated during real-time immersion. This paper compares 4 approaches calculate reduced result as fast possible: an posteriori reduction, priori enrichment method, enrichment-reduction hyperreduction.
