Truss shape optimization with dynamic response constraints

Mathematics model of the truss shape optimization design is established for searching the optimum shape of the truss,making its weight minimum,at the same time the truss dynamic response (dynamic stress of the bar sections and dynamic displacement of the nodes) constraints are fulfilled. The algorithmic is designed to solve the mathematics model with the APDL language in the soft ANSYS. Accordingly the optimum shape of the truss is achieved. The result of numerical value shows that the optimum shape of the truss achieved by this method is satisfying,and the algorithmic is steady and efficient.
