Variation analysis is a strategic task to control how dimensional and geometrical deviations, due to manufacturing processes, propagate during assembling phases. Over the years, several nu-merical methods have been proposed to model variational assemblies under the main hypothesis of rigid assembling parts. However, when parts deform during assembling operations, the flexibility of parts has to be considered into the model to better evaluate variations. A methodol-ogy called SVA-FEA and proposed by the same authors, to do variation analysis of compliant assemblies, has been already tested recently with respect to the TAA module of CATIA® CAD system, for a single-station case. In the present paper, SVA-FEA is used to perform the comparative analysis with TAA for multi-station assemblies. The main differences have been outlined, highlighting the key characteristics of the two simulation tools.

Abstract
Variation analysis is a strategic task to control how dimensional and geometrical deviations, due to manufacturing processes, propagate during assembling phases. Over the years, several nu-merical methods have been proposed to model variational assemblies under the main hypothesis of rigid assembling parts. However, when parts deform during assembling operations, the flexibility of parts has to be considered into the model to better evaluate variations. A methodol-ogy called SVA-FEA and proposed by the same authors, to do variation analysis of compliant assemblies, has been already tested recently with respect to the TAA module of CATIA® CAD system, for a single-station case. In the present paper, SVA-FEA is used to perform the comparative analysis with TAA for multi-station assemblies. The main differences have been outlined, highlighting the key characteristics of the two simulation tools.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
