RESEARCH ON FIBER PLACEMENT TOOL PRESETTING STRATEGY OF COMPLEX SIMILAR ROTATION COMPONENT

针对复杂类回转构件的复合材料铺丝成型技术领域中的对刀问题展开研究工作。对刀的策略和精度是判断构件制造精度和决定复合材料铺放成型质量的关键因素。借助设置在铺丝头压辊处的激光测距探头,通过对位于模具上不同位置对刀点或校验点的探测,进行模具制造精度校核和对刀精准性判断。基于模具回转和探测数据,提出了针对一次性低成本模具和高精度可复用模具对刀点的设置方法以及对刀策略,利用该对刀策略进行S形飞机进气道的铺丝成型实验进行验证,实验表明该对刀策略可有效解决复杂类回转构件复合材料铺丝成型的对刀问题。

In the technical field of composite fiber placement,the tool presetting strategy of similar rotation component is a key factor to judge the manufacturing precision and determine the component manufacturing quality.With the help of laser ranging probe setting at the pressure roller of fiber placement head,every tool presetting point and check point can be monitored. With those probe results,the mold manufacturing precision and adjusting precision can be checked. Based on the mold rotation and probed data,aiming at disposable molds with low cost and reusable molds with high precision respectively,this paper put forward the setting method and tool presetting strategy about mold tool presetting points. And,the experiment of S airplane inlet tape laying is carried out to validate the tool presetting strategy. The tool presetting problem of complex similar rotation component can be solved effectively by using this tool presetting strategy.
