Treffer: A selective assembly method for tandem structure component of product based on the Kuhn-Munkres algorithm.

Achieving the high performance of products generally requires high-precision assembly. Advanced machining technologies can meet the majority of precision assembly requirements, but at the cost of increased manufacturing expenses. An alternative approach is selective assembly, which can obtain high-precision assemblies by optimizing the combination means of relatively low-precision parts. Aiming at the selective assembly problem of the tandem structure component of products, the selective assembly model of tandem structure component was built by analyzing the assembly process characteristics of tandem structure component, and a novel selective assembly method based on the Kuhn-Munkres (KM) algorithm was proposed. The assembly of the rolling bearing, radial fixed shaft, and locating holes in a typical arc-shaped structure seeker servo mechanism serve as the validation object of the proposed method in this paper. The results show that the proposed selective assembly method based on the Kuhn-Munkres (KM) algorithm has a good applicability to the tandem structure component of products, which can effectively reduce surplus parts to enhance the assembly success rate and has a higher solving efficiency than the selective assembly method based on the traditional Hungarian algorithm and evolutionary algorithms.
