【摘要】 CFRP(碳纤维增强塑料)因其优异的性能，已被广泛用于宇航、导弹、火箭、飞机、汽车、化工、机械、纺织、医疗器材以及文体用品等各个领域。国外CFRP自动碳纤维带铺放工艺已经非常成熟，而该项技术目前在国内还处于起步阶段，研究开发具有我国自主知识产权的自动纤维铺放设备已成为亟待解决的课题。本课题使用Solidworks软件设计了一台用于平面铺放的龙门式碳纤维带铺放机的铺放头。它主要包括放卷装置、切割装置、加热装置、铺放压紧装置、带缺陷检测装置、测速测压装置及底纸收卷装置。包括四个轴，在切割装置上安装了三个轴(包括两个直线运动轴和一个旋转轴)，在铺放辊上安装了一个轴，这四个轴都是在微机控制下协同运动。在铺放头内有一套碳纤维带切割机构，它可以沿着任意角度对碳纤维带进行切割，采用超声波切割刀进行切割，定位精确，切割快速，保证了碳纤维带切割边界的完整性和整齐性，为当前碳纤维带的切割难题提供了一个实用的解决方法。最终的碳纤维带铺放头能够完成整个碳纤维带放卷、切割、加热、铺放、压紧、测速、底纸回收整个铺放流程。本课题以COSMOSWorks为平台，对铺放辊机构进行了有限元分析，验证碳纤维带的铺放过程中，滑块与滑轨之间的径向压力对滑块滑轨的磨损状况。本课题还分别尝试使用Animator及OpenGL两种方式，对铺放的过程和线型进行了动态仿真。Animator完全集成于Solidworks中，因此其动画制作相对容易、直观，但参数化效果差；最终侧重选择了在Visual C++平台上，使用OpenGL通过编程方式对整个铺放过程进行了仿真，在仿真过程中，铺放带可以沿着横向、纵向及斜向等不同方位对碳纤维带进行铺放，同时可以修改铺放速度、铺放角度、铺放层数等参数，实现了整个铺放过程的实时动态仿真。更多还原

【Abstract】 Carbon fiber Reinforced Plastic is widely used in military industry, rocket, aerospace, automobile, chemical industry, mechanism, textile, mechanical apparatus etc because of it’s excellent mechanical specialties. The Automatic Carbon fiber tape laying technique is very mature in the abroad; however, it is still in the initial stage in the domestic. So that it is urgent to develop our own Automatic Carbon Fiber tape machine.The paper introduces a kind of tape laying head used for depositing and compacting carbon fiber tape onto a work surface for producing a plastic article, the work surface, which is a plane with 3 meters in length and 2 meters in width. It composes of the following members: a feed reel member, a cutting member, a heat up member, a guide chute, a roller member, a tape defects detector member, a speed testing member and a take up reel member. It includes 4 movement axes. There are 3 in the cutting member (2 linear axes and 1 revolving axis) and the other 1 axis in the roller member. All 4-axis movements are CNC. There is a set of cutting mechanism in the tape laying head. It can cut the tape in any direction and an ultrasonic cutting blade is employed, which guarantees the integrity and tidiness of the cutting borderline. It provides a practical solution to the puzzle of carbon fiber tape cutting.The paper makes a FEA on the roller member in the platform of COSMOSWorks and validates the abrasion condition between the slider and the slide-rail.Additionally, the paper makes an attempt in simulating with two different methods, Animator and OpenGL. Finally, I choose OpenGL to make the final simulation, it simulates the course of the movement of the tape under the platform of Visual C++ to verify those regulations and which can lay the tape in and direction.更多还原
