The most used approach to solve tolerance analysis problems for flexible assemblies is the method of influence coefficients that combines the finite element analysis with statistical analysis in order to establish a relationship between the assembly deviation and part deviation and to foresee the statistical distribution of stresses. The key of this relationship is the sensitivity matrices for the deviations and stresses that can be evaluated by different methods of influence coefficients. Therefore, the aim of this work is to make a review of these methods applying them to evaluate some flexible assemblies on the statistical distribution of deviations and stresses.

Abstract
The most used approach to solve tolerance analysis problems for flexible assemblies is the method of influence coefficients that combines the finite element analysis with statistical analysis in order to establish a relationship between the assembly deviation and part deviation and to foresee the statistical distribution of stresses. The key of this relationship is the sensitivity matrices for the deviations and stresses that can be evaluated by different methods of influence coefficients. Therefore, the aim of this work is to make a review of these methods applying them to evaluate some flexible assemblies on the statistical distribution of deviations and stresses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
