Abstract:

In this paper, the features of cylindrical structures are analyzed, and then a scheme of 4-axis simultaneous motion controlled automated tape laying (ATL) manufacturing is advanced for them. Furthermore, the scheme is illustrated in the model of a horizontal ATL machine. By the D-H method, the paper proposes a method to calculate the feed amount of the joints during the manufacturing process of cylindrical components when the trajectory path is designed by the fixed angle method. The solution is made observing two principles: to guarantee that the pressure direction of the ATL head is parallel to the normal direction of the molding surface in the tape laying place, and to guarantee the tape is laid in a constant tape laying rate. In addition, the scheme is examined in detail in terms of system and controlling, tape laying rate, manufacture efficiency and feasibility. According to reverse kinematics, the scheme is further discussed by kinematic analysis, visual simulation and experiment trials. Finally, the conclusion is made that the low-cost 4-axis simultaneous motion controlled ATL manufacturing method can be applied to manufacturing composite components in cylindrical structures in experiments and small-scale production where requirement for production rate is not demanding.
