摘要：The conventional structural topology optimization is to design the
   structure layout with fixed external loads. In addition, the linkage
   model of components in a structure has a great influence on the optimal
   topology design of structure layout due to the load transfer function of
   components connection. This paper was focused on concurrent optimum
   design of components layout and connection in a complex structure.
   First, a new type of material model was introduced in the connective
   domain and different material distributions represented different
   connections between components. Second, the design variable is about the
   relative material density of loading-carrying domain and connective
   domain. Third, a topology optimization based the proposed approach was
   developed as well as the corresponding solving technique for designing
   structure and connection distribution. The effectiveness of the present
   design methodology and optimization scheme is demonstrated through
   numerical examples.
