中文摘要:
      针对某飞机复合材料机身整体纤维铺放加工过程中需要中间支撑装置的要求,设计了一种两轮式随动中间支撑装置。根据该装置的特点,研究了支撑轮瞬态位置信息自动生成算法:首先详细给出了依据被支撑芯模截面的CAD图形自动求解支撑轮瞬态位置的全部计算公式,并在此基础上给出了随纤维铺放层数增加支撑轮位置坐标变化的计算方法。该算法为控制系统开发奠定了理论基础。以小鹰500机身尾椎部分为支撑对象,制作了实验装置,实验情况表明该装置能够满足对大型弱刚性构件进行随动支撑的工程需求。
英文摘要:
      An auxiliary support device is required in the fiber placement process of the composite material fuselage of a certain aircraft. In order to meet this requirement, a two wheels type servo intermediate support device is designed. The automatic generation algorithm of transient position information of support wheel was researched based on the characteristics of the device. Firstly, the whole calculation formula of the transient position of the supporting wheel was given in detail based on the Computer Aid Design (CAD) pattern of the supported core-mold. The calculation method of the position coordinate change of the support wheel with the increase of fiber placement layers was given on the basis of the above. The algorithm lays a theoretical foundation for the development of the control system. The experimental device based on tail section of LE-500 aircraft as supporting is made, and the experimental results show that the device can meet the engineering requirements of following support for large scale weak rigid components.
