A Novel Topology Optimization Method for Local Relative Displacement Difference Minimization

In the topology optimization problem of mechanical structures, objectives are mainly focused on compliance minimization, displacement stress and so on. However, in practical engineering, these kinds do not meet all requirements. Some such as wind turbine blades engine aircrafts, required to maintain a superior aerodynamic shape under external loads. This puts higher requirement local deformation homogenization structure. Therefore, we proposed method for minimization relative differences considering constraints. First, present specific model method, P-Normal aggregation function is adopted deal with global constraint problem. Second, sensitive equations objective design variables derived by concomitant variables. Then, illustrate details algorithmic procedure method. Finally, validity verified two-dimensional three-dimensional examples, compared results minimization. The demonstrate that has obvious superiority potential application value differences.
