The Impact of Filter Function on Structural Topology Optimization

Based on ICM method, topological optimization model is established to minimize the weight with different constraints. The model is solved by constraint integrated method. The impact of different filter functions on continuum structural topology optimization efficiency is studied by numerical examples. The results show that: The application of nonlinear filter function can speed up the convergence, reduce the number of iterations, get a good stability in the continuum structural topology optimization.
