Abstract

A method for winding nongeodesic of ring form gas cylinder includes confirming accurate ring model first, confirming stable boundary condition of winding as per definition of nongeodesic to obtain model of nongeodesic line form, obtaining surface yarn doffing point of ring core model as per said line form and converting out yarn leaving point then generating leaving point track of yarn winding on surface of said model generating digital control code according to yarn leaving point track, carrying out fiber-winding on surface of ring core model by digital controlled winder according to digital control code.

Description

technical field [0001] The invention relates to a precise fiber winding molding method for an annular gas cylinder. Background technique [0002] The annular gas cylinder contains high-pressure compressed air, which has strong internal pressure bearing capacity and strict weight and size requirements. The existing winding technology is an approximate winding method, that is, the ring is regarded as a combination of many tiny cylinders, and the winding molding of the ring is transformed into the winding molding of the cylinder. This creates the following problems: [0003] (1) The mandrel model and the winding line type are approximate and inaccurate, so subsequent calculations and analyzes based on this are also inaccurate. This determines that the entire shaping method is an approximate method. [0004] (2) Due to the different characteristics of the inner and outer surfaces of the ring, in order to avoid slippage, the winding angle of the equihelical winding is limited ...
