OPTIMIZATION OF COMPOSITES SPINDLE-SHAPED STRUTS BASED ON REGIONAL OPTIMIZATION MODEL

Abstract

Abstract: The optimization problem of composites spindle-shaped struts used in aerospace is studied in this paper. From the structural perspective, the cross-section of the spindle-shaped strut varies along the axial direction, and from the material perspective, the strut is made of anisotropic composites. Therefore, the optimization of composites spindle-shaped struts contains more characteristics and difficulties than traditional material struts. In view of these characteristics and difficulties, a targeted regional optimization model is proposed to expand the optimization design space. An optimization process based on MATLAB and Ansys is established to realize the intelligent optimization of composites spindle-shaped struts. The results show that, based on the regional optimization model proposed in this paper, the strut weight is reduced by 39.0% compared with the initial design and 15.9% compared with previous models, which proves the feasibility of the optimization process and the superiority of the optimization model.
