STUDY ON DEFORMATION CORRECTING TECHNIQUE OF SADDLE-SHAPED CARBON FIBER COMPOSITE COMPONENT

针对鞍形碳纤维复材构件固化变形问题,通过试验的方法获取变形规律,以截面角度为参数,建立了型面各变形参数的变化规律方程,预测构件的固化变形。利用CATIA/CAA二次开发技术,实现了鞍形件的修正软件开发,并通过对鞍形件进行实际修正,减小了零件的制造误差,证明该方法可以有效地降低变形量,提高制件精度。

Aiming at the deformation of saddle-shaped carbon fiber composite component,the deformation law was obtained by experimental method.Taking the section angle as the parameter,the variation law equation of the deformation parameters was established to predict the solidification deformation of the components.By using CATIA/CAA secondary development technology,the correction software of saddle shape was developed,and the manufacturing error of parts was reduced through actual correction of saddle shape,which proved that this method can effectively reduce deformation and improve the precision of parts.
