Two Numerical Tools For Geometrical Deviation Management In Composite Assemblies: A Comparison
JOURNAL OF COMPOSITE MATERIALS(2021)
Abstract
The present work compares two numerical tools to predict the geometrical deviations of an assembly constituted by thin laminates in composite material. The first one is based on a virtual representation of both the manufacturing and the assembling processes, able to generate the variability meta-model for each component to be used in a skin-based assembly. The second one estimates the sensitivity matrix that connects the components' variations to the assembly's variations in the method of influence coefficients (MIC). They were experimentally verified on a case study. The comparison underlined the critical issue of both the tools.
