Abstract
About topology optimization,finding a good solution method for topology optimization problems is always paid attention to by the research field because they are subjected to the large number of the design variables and to the complexity that occurs because the objective and constraint functions are usually implicit with respect to design variables.Thus the guide-weight method is introduced into topology optimization.The iteration algorithms of the guide-weight method for solving problems seeking best structural performance under weight constraint and problems seeking least weight under structural performance constraint are described.Two kinds of topology optimization problems under single load case are constructed by solid isotropic material with penalization(SIMP) method and solved by the guide-weight method.Corresponding numerical examples are presented and comparison with the optimality criteria(OC) and sequential convex programming(SCP) methods employed in ANSYS is made.The examples and comparison demonstrate that the Guide-Weight method can solve topology optimization problems with simple iteration algorithm,wide availability,high efficiency and accuracy.This method provides alternative for solving topology optimization problems.
