Systems and methods for finite element based topology optimization |
摘要 |
A method is disclosed of providing an optimal minimum mass topology for a structure based on a set of design criteria including at least one support point and at least one force to be applied to the structure. The method includes the steps of: identifying a plurality of nodes within a structure design domain, and assigning an initial density value to said plurality of nodes; conducting a finite element analysis on the nodes; determining one of a stress intensity or strain energy values for each node; ranking the nodes by relative stress intensity or strain energy values; adjusting the density value for each node; and repeating the steps of conducting a finite element analysis on said nodes, wherein the step of adjusting each density value for each node is performed according to a family of statistical distribution functions that gradually transition to a bimodal distribution wherein nodes are either fully dense or effectively void thereby providing an optimal topology. |
