【摘要】：三维编织在纺织复合材料的制造中有着独特的优势，有利于增强复合材料的整体力学性能。“二步法”三维编织的应用已经比较成熟，而“四步法”三维编织受编织机械的限制，发展出现了瓶颈，延缓了其大规模的应用。特别在变截面三维编织预制件的制造上，由于预制件截面变化导致织物厚度不均匀，必须使用“加纱”和“减纱”的方法来改变变化截面编织纱线的数目。而“四步法”纵横编织编织机的携纱器是以整行（列）的形式运动，预制件的成型对编织方法的依赖非常大，并且对“加纱”，“减纱”也没有好的解决方法。为了解决“加纱”，，“减纱”难题，本文提出了主动携纱器这一新概念，即给携纱器附加动力装置，使其既能单独运动，又可以呈群组运动。如此一来提升了携纱器运行的灵活性，为编织方式的改进创造了良好条件。文中给出了以新型直线电动机为基础的主动携纱器模型，并利用Ansoft Maxwell软件对其电磁驱动力进行了仿真，验证了设计的合理性。接下来又对主动携纱器的外围装置进行了设计，给出了相应的方案。最后，本文用装置主动携纱器的编织底盘叙述了对变截面三维编织预制件的“加纱”、“减纱”流程，并分析了在此过程中纱线的相关数量关系。
[Abstract]:The three - dimensional weaving has a unique advantage in the manufacture of the textile composite material , which is beneficial to enhancing the overall mechanical property of the composite material . The three - dimensional weaving of the two - step method has been mature , and the three - dimensional weaving of the four - step method is limited by the knitting machine . In order to solve the problem of " yarn - adding " and " yarn - reducing " , this paper presents a new concept of the active yarn - carrying device , that is to add a power device to the yarn - carrier so that it can move independently and can be in group movement . In this way , the invention improves the flexibility of the operation of the yarn - carrying device , and creates a good condition for the improvement of the knitting mode . The design rationality is verified by using the Ansoft Maxwell software . Then the peripheral device of the active yarn - carrying device is designed , and the corresponding scheme is given . Finally , the knitting chassis of the active yarn - carrying device of the device is used to describe the yarn - adding and yarn - reducing flow of the three - dimensional braided preform with variable cross - section , and the relevant quantitative relation of the yarn in this process is analyzed .
