Unformatted text preview: hing all these boundary conditions, we solve system made of these equations and equation 3. Obtained results are relations linking actual position of components and geometrical parameters. Symbolic writing of the relations gives the possibility to have influence factor of each parameter on point positions. Geometrical Study of Assembly Behaviour 307 4 INDUSTRIAL STUDY 4.1. Presentation The above method has been applied to an industrial case that consists in assembling a large compliant door on a structure of helicopter. The door shown figure 8 is to be open and closed many times. Four fixation points (P1,P2,P3,P4) of the door on the structure have been chosen. A set of seven adjusting devices (X2, Y1, Y2, Y3, Y4, Z1, Z2) is available behind the panel the value of whose we search. P4 P1 Y4 Y1 Z2 Z3 X2 Y3 P2 Y2 P3 Figure 8: Nominal panel The actual geometry of the panel is measured and does not exactly match the nominal geometry, we present in this paper the method for a given actual geometry. All around this panel a seal assur...
