The Modified Homogenization Method with Density Threshold for Structure Topology Optimization

摘要：

There are some disadvantages in needing long computing time and easy to bring immature convergence when the topology optimization is used for some complicated structures body optimization with the homogenization method. A modified iterative method is designed to improve the disadvantages according to the calculation character of topology optimization. This modified method takes two density thresholds-MFs and MFL to control the topology optimization process. At the same time, the cliaracter and the value domain on density threshold are studied. The examples show that the modified iterative method is simple and practical.
