Using computer models spatial dimension chains and database of virtual assemblies for improvement of assembly operations performance

The coupled three dimensional chains defining the precision parameters of assembly was built for the mounting of power plant on the helicopter’s airframe. For the assembled structure the dimensional forward and inverse problems were stated and numerical algorithm of its resolving was developed. Considering as the “grey box” the 3D dimensional chain with known architecture but unknown sizes of each parts we created the database of the virtual assemblies which was used to find the assembly – analog, and further to the synthesis of one step setting of the moving compensators at mounting of the real world aggregate.
