Abstract:

For complex and closed profile parts, the traditional trajectory planning algorithm of isometric offset in fiber placement is difficult to generate both higher accuracy of trajectory angle and trajectory interval. This easily causes the deviation between actual placement angle and designed fiber ply angle. To overcome this problem, an angle control algorithm of trajectory planning is presented in this paper. This algorithm combines the uniform angle ridge-line-type datum algorithm of generating initial trajectory with the geodesic-type isometric offset algorithm to generate batch trajectories. And the algorithm has the advantages of both higher accuracy of generating initial trajectory and higher efficiency of generating batch trajectories. It can also control the angle of trajectories to ensure that each trajectory meet the requirement of the angle. This decreases and eliminates the difference between actual placement trajectories and designed placement trajectories. Angle control algorithm not only could ensure the accuracy of trajectory angle and trajectory interval, but also could improve the efficiency of generating batch trajectories. Then, the relevant software is developed based on the Component Application Architecture (CAA) technology of CATIA and Visual Studio 2005. And the algorithm has been successfully validated to plan the trajectory of the airplane's S-shaped inlet by using the developed software.
