Inclined winding is a new fiber belt winding technology proposed by technicians for the production and manufacture of high-speed aircraft with conical shells. In order to meet the trajectory path planning of inclined winding technology, a spiral algorithm for inclined fold winding is proposed considering the designability of process parameters such as inclined fold angle and stepping distance. For the cone or pyramid with the central axis, the spiral slice algorithm is used to obtain the path points of an oblique winding according to the actual core model, including the establishment of a reference line, reference track point, inclined winding angle, oblique winding center track point and path point information acquisition. Finally, using Visual Studio 2019 as the development platform and VB.NET language, the pathplanning software of the algorithm is programmed. The trajectory simulation and experimental verification are carried out on the path of inclined winding prepreg fiber belt for cone and pyramid. The verification of the effect diagram proves the feasibility of the algorithm.

The composite cylindrical shell pressure structure is widely used for autonomous underwater vehicle (AUV). To analyze the critical buckling problem of variable stiffness (VS) composite pressure structure of AUV, a discrete finite element (DFE) method based on the curve fiber path function is developed in this work. A design and optimization method based on the radial basis function surrogate method is proposed to optimize the critical buckling pressure for a VS composite cylindrical shell. Both the DFE and surrogate methods are verified to be valid by comparison with the experimental data from the listed references. The effects of the geometric parameter and fiber angle on the critical buckling pressure are studied for different cylindrical shell cases. The results indicate that the proposed simulation model and optimization method are accurate and efficient for the buckling analysis and optimization of a VS composite cylindrical shell. Optimization result shows that the optimum critical buckling pressure for the VS cylindrical shell is improved and is 21.1% larger than that of the constant stiffness cylindrical shell under the same geometric and boundary condition.

“…In this work, the design variables considered were the alignment of the stiffeners and the thickness of the layers. Moreover, using Genetic algorithm, Song et al, 5 Chun and Guang, 6 Molavizadeh and Rezaei, 7 and Wei et al 8 studied the optimization of composite cylinders under hydrostatic pressure to delay the onset of buckling and failure. In another work, Almeida et al 9 studied the axial and torsional buckling response of carbon-epoxy filament wound-laminated drive shafts with different layups.…”

In the notched structures, to achieve maximum buckling resistance in comparison with structural weight, the optimal design of a stiffener is very important. In this research, after a review of the existing literature, nonlinear buckling behavior of composite plates containing the cutout with three different designs of stringer was investigated. The considered stiffeners are planer, longitudinal, and ring types. The buckling experiments were carried out on the stiffened plates containing a circular notch. Moreover, to achieve an efficient prediction of the buckling in the stiffened laminate with the hole, a finite strip method is developed based on the Airy stress function and von Karman’s large deformation equations. Studies show that there is a good agreement between the postbuckling behaviors derived from developed finite strip method with experimental results. Fast convergence of the considered finite strip method compared with the finite element results shows its efficiency for prediction of buckling behavior in laminated composites. The results show that the buckling load-bearing capacities of perforated plates with a longitudinal and planer stiffener are higher compared with the other stiffener, respectively. The detailed parametric study on the effects of thickness of the plate and stiffener and opening diameter on buckling behavior was performed using experiments and modeling.
