【摘要】 在分析三维五向编织纱线运动规律的基础上，将复合材料箱体设计为由编织底座和箱体壁两部分拼接的结构；在此基础上，得出了三维五向复合材料拼装箱体的编织和成型原理；根据编织原理和纱线运动规律，建立了拼装编织箱体的三维实体模型；对三维五向复合材料拼装箱体进行有限元分析，并通过应力和应变分析结果研究了编织复合材料箱体中基体和纤维的受力。在忽略摩擦、轴承等因素对系统影响的假设下，建立了考虑箱体两级齿轮传动系统的运动方程组，通过龙格-库塔法对两级齿轮传动系统进行数值分析，研究了激励对拼装编织系统动态特性的影响。更多还原

【Abstract】 On the basis of analyzing the movement law of the three-dimensional and five-direction braided yarn, the composite box was designed to be composed of two parts of the braided base and the box wall. On this basis, the braiding and forming principle of the three-dimensional and five-direction braided box was obtained. According to the braiding principle and the yarn movement law, the three-dimensional solid model of the braided box was established, and the finite element analysis of the three-dimensional and five-direction braided box was carried out. The stress of matrix and fiber in the braided composite box was studied by stress and strain analysis results. Under the assumption of ignoring the influence of friction, bearing and other factors on the system, the motion equations of the two-stage gear transmission system with a box body were established, and the numerical analysis of the two-stage gear transmission system was carried out by the Runge-Kutta method to study the influence of excitation on the dynamic characteristics of the assembling and weaving system.更多还原
