Preliminary research on structural dynamical design based on evolutionary structural optimization method

A new idea of structural dynamical design and a development technology of optimization program based on ANSYS platform were proposed by using the evolutionary structural optimization method and structural efficiency. A single objective, multi-constraint optimization model was created by incorporating the dynamical design parameters of mass, stress, displacement and frequency; and the constraints were considered separately at the start of the study. The feasibility of this method and reliability of the program were proved by some examples, of which the final topology, evolution and variation of parameters were similar to the previous research under the same conditions and without consideration of influences caused by numerical instability.
