The Application of Topology Optimization Theory in Three-dimensional Radial Gate Design

Topology optimization, also known as structural layout optimization, the basic idea is a design method that looking for the most optimal distributing form structural stiffness in design space or the best way to pass power, in order to achieve optimization of some behaviors or alleviation of the structure weight. Used continuum structural topology optimization theory, and carried out pioneering research to the optimization design in complicated three-dimensional radial gate. The problem of checkerboard format, grid-dependent and the local extremum existing in topology optimization process was solved, optimal results is relatively satisfactory.
