Assembly Sequence Planning Method for Compliant Assembly
نویسنده
چکیده
Compliant assemblies are widely used in automobiles and airplanes etc. In order to simplify the complex assembly sequence planning problem of compliant assemblies involving dimensional variation caused by deformation, a two-step assembly sequence planning method is proposed in this paper. Meanwhile, an example of a wingbox assembly is used to explain the principle of the method. In the first step the wingbox is assumed to be a rigid body without deformation. The assembly sequence is then acquired according to the precedence constraint relationships represented by the liaison graph and the adjacency matrix. On the basis of the result obtained in the first step, the assembly sequence which meets the dimensional quality requirements is acquired by dimensional variation analysis in the second step. In order to clearly express the precedence and hierarchical constraint relationships for large number of parts, the hierarchical liaison graph based on connection feature is proposed and applied on modeling the wingbox assembly.
