Abstract
The constant winding tension can make the filament arranged in order. The stress distribution between the filament balance fully gives play to the enhancement of filament, and increases the intensive workload of the composite winding material. This paper conducts the mechanical analysis for the unwinding roller and tension measuring roller of the cylindrical winding machine so that gets the mechanical model, gives error compensation formula caused by the radius change of the yarn group in the unwinding side, designs the closed-loop control system and utilizes the dynamical- integral PID control strategy to achieve the tension control during the process of the cylindrical winding.
Highlights
The winding process consists of the production of mandrel and lining, the disposition of the glue solution, the filament drying, heat treatment, winding, solidification, testing, and reconditioning [1]
The constant winding tension can make the filament arranged in order and the stress distribution between filament uniform, it is beneficial for implementing the enhancement of the filament and increasing the workload of the composite winding product, otherwise it will result in more than 20 percent of the damage for the strength action of the filament
During the winding process, when the acceleration or deceleration motion caused by certain elements occurs, to ensure the uniform speed of winding the yarn, the speed compensation is required for unwinding roller
Summary
The winding process consists of the production of mandrel and lining, the disposition of the glue solution, the filament drying, heat treatment, winding, solidification, testing, and reconditioning [1]. Ren Qile designed and set up the tension control system in his doctoral dissertation, regarding the winding roller and swing rod as the object of study respectively. They deduced the computational formula between the winding pre-stress and the cooling temperature of composite layer and utilized the general finite element software to study the influence of the winding tension on the stress of the round winding composite gas bottle based on the equivalent cooling method. This paper utilizes the dynamical-integral PID control strategy to achieve the control for the winding tension
