Abstract:

A quasi analytic method for solving structural optimization problems is developed by coordinated use of mathematical transformations, high quality approximation and two level approximation strategy. The method, which has the advantages of both generality in application and high efficiency in computation, is especially of benefit to large practical design problems. Typical examples of different sorts are optimized to test its power.

Key words: structural optimization, design method, CAD
