【摘要】 纤维缠绕机自身的发展,带动了纤维缠绕工业的不断扩大和增长。最开始的缠绕机都是机械式的,比较适用于一些大量生产定型制品及一部分形状比较简单的制品,它具有结构简单、传动可靠、维修方便、制造容易及投资少等优点,因此仍大量使用且在继续发展中。本课题的主要研究内容是：对球形容器的缠绕规律进行分析,并利用机械式缠绕机来缠绕FRP球形压力容器这种稍微复杂一点的容器。本论文首先研究了适合球形容器的缠绕规律,针对具体的球形容器,计算出了适合的缠绕线型、缠绕角及相应的转速比,然后进行了球形容器的机械式缠绕机的结构设计。根据芯模和绕丝头相对运动的不同,缠绕机可分为：芯模旋转,绕丝头平移；芯模平移及旋转,绕丝头旋转；芯模平移及旋转,绕丝头不动；芯模不动,绕丝头平移及旋转等型式。本文中的机械式缠绕机是芯模旋转,绕丝头平移的运动方式,但是由于球形容器的特殊性,绕丝头除了平移运动之外,还需要有前进后退的运动,这个运动是通过小车联动机构上的伸臂通过连杆的运动来实现的,并且为了机构运动的稳定,本论文中的机械式缠绕机是由一个电动机来带动主轴和小车的运动。另外还设计了一套挂轮箱机构来进行调速,并计算了缠绕同一球形容器,当纱片宽度改变时,机械式缠绕机的挂轮箱中的传动比的变化。本文以Pro/E为平台,利用其强大的参数关联和尺寸驱动功能对整个缠绕机设备建立了零件图、装配图、工程图的模板,保证整个设计过程设计参数的关联性以及在三者之间设计信息的传递,然后通过这些模板建立了三维模型,建立了一套适合缠绕球形容器的机械式缠绕机。同时,本论文中利用Pro/E中Pro/Mechanism模块对机械式缠绕机中的小车联动机构做出了缠绕过程的运动仿真,使小车运动的整个过程更加直观,希望对指导实际的生产过程会有一定的帮助。最后本文采用了ANSYS软件中比较强大的有限元分析功能,对缠绕机中的一个零部件结构进行了有限元分析,并与理论计算结果相比较,证明了设计的可行性和可靠性。更多还原

【Abstract】 The development of fiber winding machine’s,drive the fiber winding industrial to expanse and grow. The first winding machines are mechanical, that are more suitable for the mass production for the shaped products and some simpler products. It is simple in structure, reliable transmission, convenient maintenance, easy manufacturing and less investment etc, and therefore still in large use and in continued development. The main research contents of this topic are analysis the fiber winding law of spherical presure vessel, and using mechanical winding machine to wind FRP spherical pressure vessel, which is slightly more complicated container.Firstly, this paper study the winding rule for spherial vessels, and calculate the suitable winding linear, winding angle and the corresponding speed ratio of the specific spherical container, and then design the structure of mechanical winding machine of spherical containers. According to the different relative motion between mandrel and filament, the winding machine can be divided into such types:the mandrel rotates, the filament translates; the mandrel rotates and translates, the filament rotates; the mandrel rotates and translates, but the filament doesn’t move; the mandrel doesn’t move, the filament translates and rotates. In the text the winding machine works with the mandrel rotating and the filament translating. But due to the particularity of spherical container, apart from the translation motion, the filament also has the forward and backward motion. It is realized by the arm in the car linkage institutions with connecting rod movement. And for the sake of the stability mechanism motion. The mechanical winding machine of this paper is driven by a motor car to led the movement of spindle and car, and we design a set of wheels box to speed regulation, and calculate the transimission ratio of the mechanical winding machine’wheels box,when winding the same spherial vessels, but change the wideth of yarn piece. The text is completed with the platform called "Pro/E" software, we designed the parts graph and assembly drawing of the winding machine, using the mighty parameter associations and dimension driven function of the software. We ensure the relevance of parameters in the whole design process and the information transfer between them, then we designed 3d model through these templates.This text also makes a statement about the corresponding transmission ratio when the width of the winding yarn piece changed.At last we make a simulation about the winding process using Pro/E Mechanicanism module, which make the whole process more intuitive. We hope this can be helpful to the practical production.This paper use ANSYS software that has powerful finite element analysis of important complex function, analysis the finite element of mechanical part, and compare the actual to the theoretical calculation result, and to prove the feasibility and reliability design.更多还原
