| Abstract: |
| In order to improve the buckling stability, this paper employs the methodology of solving salesman traveling problems by ant colony algorithm to optimize the stacking-sequence of the filament wounded case. First, this paper explains the essence of stacking sequence optimization is adjusting the stiffness distribution along the thickness direction to improve the bending stiffness and the load path, thru which the stability of the composite structure can be enhanced. Then, an automatic grouping and coding technique is proposed, which adapts the classic ant colony algorithm to the process technics constraint and improves the computational efficiency by reducing the number of cities. The validity and the superiority of the method are verified via a classic example. Finally, the program developed has been successfully used to improve the buckling stability of a composite case. |
