Aiming at the need of fiber composite cylinder winding, test the cylinder longitudinal fiber winding by horizontal fiber winding machine. According to fiber equipment structure design, analyze the winding feature, establish longitudinal winding math model, calculate fiber winding angle, realize the automation movement of cylinder longitudinal fiber winding by horizontal fiber winding machine based on NC programming. The test results show that the fiber arrangement meets the CNG cylinder winding precision requirement, and satisfies the operation requirement of fiber composition material cylinder winding, and verify the feasibility of cylinder longitudinal fiber winding by horizontal fiber winding machine.
