摘要: 为解决目前手工增强缠绕碳/碳坩埚预制体无法保证产品一致性及生产效率低下的问题,设计了一种碳纤维增强坩埚预制体柔性缠绕成形系统。基于非测地线法提出了适用于一端平面封头一端椭球封头特殊回转体结构坩埚芯模的线型设计流程,介绍了计算机辅助线型设计的各个模块及实现方法,并对设计线型进行了仿真;根据缠绕特性设计了四自由度专用缠绕机运动机构,基于可编程控制器和触摸屏设计了四自由度缠绕机控制系统,并进行了碳纤维增强缠绕实验。实验结果表明:缠绕机运行稳定,纤维可连续稳定地缠绕在芯模表面,所设计的系统可实现碳纤维增强碳/碳坩埚预制体的自动化缠绕。

Abstract: In order to solve the problems of product consistency and low production efficiency caused by manually reinforced carbon/carbon crucible preforms, a flexible winding forming system of carbon fiber reinforced crucible preform was proposed. The line type design process of crucible core die for special rotary body structure with one end plane head and one end ellipsoid head was presented based on the non-geodesic method. Each module and implementation method of computer aided line type design were introduced, and the design line type was simulated. A special winding machine with four degrees of freedom was designed according to the winding characteristics. The control system of four-axis winding machine was designed based on programmable controller and touch screen, and the winding tests were carried out. It is indicated that the winding machine runs stably and the fiber may be wound continuously and stably on the surfaces of the core die, and the system may realize automatic winding of carbon fiber reinforced carbon/carbon crucible preforms.
