Assembly sequence influence on geometric deviations propagation of compliant parts (original) (raw)
Abstract
This paper presents a non-rigid part variation simulation method for fulfilling functionnal requirements on compliant assemblies. This method is based on the propagation of different geometrical deviations (manufacturing and assembly process defects) using the Method of Influence Coefficient. Tolerance analysis of compliant assemblies is also achieved very early in the design stage. As a consequence, designers and manufacturing engineers can efficiently analyse the assembly design principles both in terms of installed stresses and geometric variation clearance. They can also set optimised' sequences that enable to get rid of geometric variations.
