Topology design optimization on truss-like continuum with minimum displacement

LI Baolong,ZHOU Kemin(College of Civil Engineering,Huaqiao University,Xiamen 361021,Fujian,China)  
To expand flexibility minimization problem in topology optimization to general displacement minimization problem,the design domain is meshed by finite elements and the truss-like continuum is used as the material model,and the rods are assumed to distribute continuously in design domain.The density and orientation of rod at node position are selected as design variables.The displacement along the specific direction is selected as the objective function.The continuum distribution field of members is optimized to form truss-like continuum by optimality criteria method based on the gradient of objective function.By the aid of structural mechanics conception,the parts of members are remained to form topology optimization frame.
