Abstract
This disclosure is generally directed to 3D tolerance analysis. In one exemplary method, a combination of a variation analysis procedure and a finite element analysis (FEA) procedure is executed by a computer. The variation analysis procedure involves determining a first simulated force for effecting a mating between a first surface of a first part and a first surface of a second part. A first set of deformation parameters is determined by applying the first simulated force to the first surface of the first part. The FEA procedure involves determining a second simulated force for effecting the mating between the two surfaces based on one or more assembly loads. A second set of deformation parameters is determined by applying the second simulated force to the first surface of the first part. Various deformation parameters of the mated assembly can be obtained by combining the first and second set of deformation parameters.
