摘要
针对基于复杂自由曲面类构件的复合材料铺放成形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模具制造精度和决定复合材料铺放成形质量的关键因素。借助设置在铺放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。基于激光测距探头所探测数据,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翼身融合体的铺放成形实验进行验证,实验表明该对刀策略可有效解决复杂自由曲面类构件的复合材料铺放成形的对刀问题。
In the technical field of composite fiber placement,the tool presetting strategy of free surface component is a key factor to judge the mould 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 checking point can be probed.According to those probe results,the mould manufacturing precision and adjusting precision can be checked.Based on the probed data,aiming at disposable moulds with low cost and reusable moulds with high precision respectively,we propose the setting method and tool presetting strategy about mould tool presetting points.And the experimental free surface fiber placement is conducted to validate the tool presetting strategy.The tool presetting problem of complex free surface component can be solved effectively by using this tool presetting strategy.
