By the same way, actual geometric deviation modify distance between the 2 components hence the boundary conditions values. Our model takes into account this influence. These vector form deviation noted (uF(i), vF(i), wF(i)) can be found in equations associated to the mechanism. Figure 7: Actual geometry deviations and there influence on boundary conditions If we consider component 1 actual geometry deviation, we can write equations expressing this influence: d1 Fx (1) = S .( Lini - lnom (1) − .v M (1) - v F (1) ) d1 + d 2 with ∆x[1] given by experimentation, for example: vF(1)= 0,5 S .d 1 Fx (1) = S .( Lini - lnom (1) - 0,5) − .v M (1) d1 + d 2 forces ⎤ ⎡ Where Fx(1) belongs to ⎢ ⎥ matrix and vΜ(1) belongs to [V] matrix. ⎣displacement ⎦ Once establis...
