Abstract: A ultrasonic welding method of joining dissimilar-material workpieces, such as sheet materials, and the joined components formed thereby. The method includes applying ultrasonic energy to a thermoplastic piece to fill a hole of a dissimilar piece to form a weld point that is made up with polymer from the thermoplastic piece. In general, the geometry of the thermoplastic piece is not altered during the process. The dissimilar piece generally has a higher melting temperate and can be metal, thermoset polymers, or other thermoplastic material. The welded pieces can be arranged in a lap, laminate, or double lap configuration. In some embodiments, the hole of the dissimilar sheet material includes undercut features that improve the mechanical interlock between the dissimilar pieces. In some embodiments, the weld point has a mushroom cap to improve mechanical interlock.

Abstract: A method for generating a candidate assembly system layout for an assembled product includes inputting a bill of materials including a list of components for the assembled product and determining a plurality of assembly patterns for the assembled product including a plurality of intermediate assemblies and sub-assemblies. A basic task layout is determined that includes assembly tasks for assembling the assembled product based upon a selected one of the assembly patterns. A whole task layout is determined based upon the basic task layout for the selected assembly pattern. Candidate assembly machines are selected for the whole task layout, and zoning constraints are identified for the candidate assembly machines related to assembly tasks. A candidate assembly system layout is generated based upon the whole task layout, the selected candidate assembly machines and the zoning constraints, from which a simulation model of a candidate assembly system is generated.
