“…In Ref. [12], by means of netting theory optimization, the influence of fiber preload stresses considered as independent variables for the liner and composite double shell was investigated at different preload pressure, working pressure, test pressure and burst pressure. SU Weiguo et al [13] considered fiber winding process as continuous superposition of pre-tensioned composite thin rings, and the residual stress of winding layers was analyzed on the basis of anisotropic composite elastic theory and isotropic cylinder elastic theory.…”

In order to obtain the distributions of residual prestress of the filament wound composite barrel with non-round section for railgun caused by the winding tension, a new numerical approach is provided. Based on the idea of considering the fiber bundles as the main load-bearing material for each winding layer, the loading of the initial winding tension in the winding process can be simulated through loading the initial tensile stress of the fiber bundles in fiber direction of the winding layers’ elements. Firstly, combing with the element birth and death technology, a three dimension finite element model for a hybrid filament wound cylinder with metal liner is established to simulate its residual prestress caused by winding tension. Its results are compared with the ones obtained by the theoretical model, which verifies that this numerical simulation method is reliable to some extent. Then, this numerical simulation method is adopted to analyze the residual prestresses of the filament wound composite barrels with non-round section for railgun, which are under three different winding tension control modes respectively. The results can provide some references to the initial design of the filament wound composite barrel with non-round section for railgun.

The paper demonstrates a technique that combines the use of artificial intelligence and the finite element method to analyze the production process of the liner – the seamless part of composite overwrapped pressure vessels obtained by tube forming. Instead of expensive physical experiments, computer simulation was used, which made it possible to quickly obtain "big data", including the main technological parameters of tube forming process, some metal flow features and the tendency for defects to appear. The processing of the data array was carried out in MATLAB using neural networks and a genetic algorithm for the multi-objective optimization problem. As a result, the influence of technological parameters on the formation of the liner geometry was determined, and the optimal variant of their manufacture was proposed, which is of practical interest to companies producing metal-composite cylinders.
