基于偏心理论的异型构件编织工艺推理方法
Braiding process reasoning method for special-shaped components based on off-center theory
摘要
Abstract
In order to realize accurate and autonomous production of braided preforms for special-shaped composite com-ponents,a process reasoning method for braiding special-shaped components based on the off-center theory is proposed.The off-center braiding parameters are proposed and the yarn deposition pattern under the off-center braiding is analyzed.The position equation of the yam falling point on the surface of the mandrel is established based on the response function of the convergence length over time.The surface contour features such as vari-able cross-section,large curvature of the profiled member are reconstructed by applying the model reconstruc-tion algorithm.The optimized design of the yarn distribution is carried out based on the contour features,and the reasoning for the process parameters such as the braiding speed,the take-up speed,and the trajectory are realized.The results show that the process reasoning method reduces the coverage difference between the inner and outer sides of the mandrel by 68.9%,and significantly improves the consistency of braided special-shaped preforms.关键词
