Non-rigid geometry variation for fabricated aero structure (GeoVar)

Start date: Apr 1, 2014, End date: Mar 31, 2016,

In traditional 3D variation simulation (stack-up’s) it is common to consider that the parts are rigid. However, often in production forces are applied manually or by different fixturing solutions to assure that requirements on offset are fulfilled before welding parts together in an assembly. This causes the parts to bend and rigid analysis is therefore not valid. Depending on assembly sequences a ...
