THE DEVELOPMENT OF A NEW TENSION CONTROL SYSTEM FOR AUTOMATED FIBER PLACEMENT MACHINE

Abstract

Abstract: Automated fiber placement is an important composite fabrication process, in which fiber tension is an important process parameter to affect the quality of the products. This paper develops a closed-loop tension control system which uses DSP as the control unit, tension brake and low-friction cylinder as the execution unit, linear displacement transducer as the feedback unit. The mathematical model is established, while the hardware and software platform of the tension control system is set up. Works on constant tension, tension step response and speed step response were carried out based on the proposed platform. Experimental results show that the proposed tension control system responses fast and the tension fluctuation rate is low, which could satisfy the requirements of the tension control for fiber placement.

Key words: fiber placement, tension control system
