At present , there is no cad / cam software for non - axisymmetric filament winding in china . this paper researches into method to design fiber paths of non - axisymmetric filament winding , generalizes splines in traditional cagd , successfully applies them to the fiber path design of winding elbows , presents mathematical principles and methods of winding elbows , and develops a cad / cam system for elbow fabrication 本文研究了非轴对称缠绕的纤维路径设计方法，推广了传统cagd中的样条技术，并成功地应用于缠绕弯管的路径设计中；提出了复合材料弯管的纤维缠绕数学原理和方法，并研制开发了一套缠绕弯管cad cam系统。
To develop the finite element analysis method in solving the composite material multi - layer fiberfilament winding case in pressure vessel , a easy method to exactly solve the correct result is given which is called elements " birth and death " method 摘要为更准确地应用有限元分析方法解决树脂基复合材料纤维缠绕的小型压力容器的强度问题，文中提出利用“单元死活”模拟纤维缠绕过程的简易有限元数值计算方法，并通过使用这种方法对复合材料等强度缠绕的某型号小型压力容器进行计算模拟，证明方法的正确性。
He had gone to osip alexyevitchs house on the pretext of sorting out the books and papers of the deceased . simply he was in search of a quiet home of rest from the storm of life , and his memories of osip alexyevitch were connected in his soul with a whole world of calm , solemn , and eternal ideals , in every way the reverse of the tangled whirl of agitation into which he felt himself being drawn 他藉口清理死者的书籍和文件而到约瑟夫阿列克谢耶维奇的府上去，仅仅是为摆脱人生的困扰而寻找慰藉，并且，回忆起约瑟夫阿列克谢耶维奇，就会同一个充满永恒宁静庄严思想的世界联系起来，这些思想与他感到自己被缠绕的令人不安的那团乱麻，是截然不同的。
By framing reasonable technology and plenty of repeating experiment , the main contributions have been made as follows : 1 ) the analysis of differential scanning calorimetry ( dsc ) was made on the bmi resin , qy8911 - ii . curing reaction of the qy8911 - ii was studied by dsc . the effect of heat history on the resin was discussed and the adequate parameters for filament winding technology were determined . 2 ) the study on preparation technology of prepreg strands was carried out 通过制定合理的工艺和大量的反复实验，主要完成了以下三方面的工作： 1 )针对缠绕工艺特点，对qy8911 -双马来树脂进行了差示扫描量热法( dsc )分析，通过测试数据及对大量数据分析，确定了用qy8911 ?进行加热缠绕的合理工艺窗口，指明了用qy8911 -进行加热缠绕工艺的可行性； 2 )开展了预浸纱制备工艺实验研究，通过反复调试获得了满意的工艺参数，制备出了满足工艺要求的预浸纱，为m46j / qy8911 -缠绕复合材料的研制奠定了基础。
