A new general method for assigning frequencies with low spillover through structural modifications

By modifying the mass and stiffness parameters of a structure, subset its natural frequencies can be assigned. However, such an assignment is usually accompanied with changes remaining frequencies, known as ‘spillover’. Eigenvalue or frequency spillover often needs to avoided in engineering. In this paper, new general method proposed for assigning structure low level through structural modifications. The combines multi-population genetic algorithm radial basis function neural network implemented MATLAB-PYTHON-ABAQUS data interaction system. It suitable theoretical models (for example, finite element models) structures. means three numerical examples, ability assign subsets discrete discretised continuous structures while maintaining demonstrated.
