Comparison between two Generation of consistent skin model shape based on a linear and nonlinear simulation of analysis tolerancing of flexible assembly with the consideration of spot welding effects

Tolerance analysis for flexible parts and assemblies is a precious implement for minimizing manufacturing costs. This paper reviews two major methods for tolerance analysis for flexible parts. The methods discussed are a nonlinear Method Monte Carlo (MMC) and a linear method Influence Coefficient (MIC). For more performance and to approach the real case, the proposed model has been simulated to predict the deformation of flexible parts taking into consideration of spot welding effects as well as the contact modeling. Through a comprehensive comparison of these methods, this paper will present a study case a simulation of two parts using the proposal approach.
