Abstract:
A novel method for assembly sequences planning is proposed based on the
theory of directional connection graph. By introducing the directional
graph into represent the mating conditions of parts in a product, a new
model of product representation, directional assembly connection graph (DACG),
is constructed. Then the properties of DACG are given. The directional
cut set analysis based on DACG is brought forward to generate assembly
sequences. Compared with cut set analysis, the new method generates less
invalid sequences, and has less computational complexity. In order to
reduce the invalid sequences further, the directional cut set analysis
of monotone and linear assembly is studied. The approach to add
constrains on the assembly sequences generation algorithm is discussed
also. Analytical and experimental results are presented to demonstrate
the effectiveness of the approach.
