摘要
五轴联动数控纤维缠绕机的研制成功,对缠绕工艺而言是一次技术性的飞跃。在一些复合材料缠绕成型工艺的研究中,一项重要的内容就是对施加在纤维上的张力进行精准地控制,以防止缠绕制品因张力的不合适而引起制品变形过大,从而降低制品强度和抗疲劳性能,影响制品的质量。本文的目的是研发一种新型的五轴数控纤维缠绕机,通过对五轴联动数控纤维缠绕机的整体结构的设计,以及对缠绕机张力控制系统的工作原理的分析和研究,设计了五轴联动数控纤维缠绕机的张力系统。该系统采用曲线拟合的数学描述方法实现对张力传感器的标定,再通过复合滤波消除干扰。该缠绕机在实际的使用过程中,精确且稳定,制品满足使用要求。
The successful development of the five-axis NC fiber winding machine is a breakthrough of winding machines.In the process of the winding and shaping of composite material products,it is important to precisely control the tension on the fiber,so as not to deform the products and affect their quality. In this study,we designed a new-type five-axis NC fiber winding machine. Through analysis of the working principles of the tension control system,we designed a tension system that used curve fitting for tension sensor calibration,and composite filtering for interference elimination. The winding machine is accurate and stable in practice,and its products meet the production requirements.
