Popis
Shrnutí:In the field of structural optimization, reasonable selection of parameters and obtaining optimized solutions are key issues. This paper proposes a multi-objective optimization method for static displacement based on the Projection Parameter Sorting Method (PPSM). This method sorts parameters based on the projection characteristics of the parameter sensitivity vector, and uses the Epsilon algorithm and improved Neumann series to calculate the structural static sensitivity. Through iteration, combinations are selected and parameters are corrected according to a given number of parameters, and it is applicable to multi-objective problems with limited parameters. In the example, this method has a significant optimization effect on truss structures and is superior to the optimization results of random parameter selection. What are the common optimization methods in the field of multi-objective optimization of static displacement? How to determine the number of parameters in the projection parameter sorting method? Share some practical cases of structural optimization.
