The Method of Tension Control with Gravity Balance

Article Preview

Abstract:

Carbon fiber is a fiber material, so the tension must be kept constant in the placement process. The attitude of carbon fiber placement head will change with the change of a placement path. Focusing on the problem of tension fluctuation caused by the attitude of carbon fiber placement head, gravity balance characteristic of symmetrical objects is adopted to propose a tension control method for eliminating the tension fluctuation and tension measuring error caused by gravity. In this way, the tension is kept constant depending on tension feedback control. Mathematical model and theoretical analysis show that the tension control method with gravity balance can eliminate the gravity influence on tension and make the tension keep constant.
