Abstract
A computer-implemented method for reducing spot welds in a parameterized workpiece model includes generating a new design space (DS) from an original spot weld DS. The new DS includes a plurality of spot weld locations from the parameterized workpiece model with the original spot weld DS. The new DS is optimized to have a fewer number of spot weld locations than the original DS. The processor identifies a plurality of offending spot weld locations of the remaining spot weld locations in the new DS and a plurality of conforming spot weld locations of the remaining spot weld locations. The processor removes all but one optimized extension candidate from processor-selected groupings of welds while enforcing a minimum distance requirement. The processor outputs an inter-distance constrained parameterized workpiece model with an optimized extension candidate in each of the plurality of extended DSs to an operatively connected output processor.
