| Abstract: | This paper investigates the multi-object optimization for a spatial 6-DOF (degree-of-freedom) cable-driven parallel manipulator. The optimization based on an NN (neural network)-genetic algorithm was carried out respectively with regarded to workspace volume, the minimum tension and global dexterity index, then three groups of satisfactory solutions were obtained. Furthermore, the weight coefficients for the multi-object optimization model were gained through the grey clustering method. The results show that the NN-genetic algorithm is effective for the structural optimization and can provide a useful reference for the optimal design of similar manipulators |
| Keywords: | cable-driven parallel manipulator multi-object structural optimization neural network genetic algorithm grey clustering method |
