Hydraulic cylinders are used in many different areas from aviation to construction machinery and are generally manufactured using conventional steels that stand out with their low strength to weight ratio. In this study, it was aimed to design a hydraulic cylinder using composite materials to reduce cylinder weight. In this context, a novel composite hydraulic cylinder was designed, and numerical analyses for the composite portions of the hydraulic cylinder were carried out. For the numerical model, an aluminium liner and cylinder heads with the geodesic dome profiles were used, and composite layers were formed on their surfaces by using the Ansys ACP module.

Pressure vessels are subjected to stresses in axial and radial directions during their service life, which causes undesirable damages. For that reason, it is highly important to design the fiber directions in composite overwrapped pressure vessels in such a way that can carry the loads occurring in both directions. In this context, composite pressure vessels with 20 mm polar opening radii were designed and the geodesic dome profile was obtained by solving the elliptic integral. Helical and hoop winding layers were used together on the cylinder surface and the effect of stacking sequence on the structural performance was examined. In the current study, numerical models with six different stacking sequences were defined and thus stress, strain and failure indexes were determined. Furthermore, the effects of hoop winding layers on the mechanical properties were investigated by comparing with the numerical model consisting of completely helical winding layers. As a result of the current study, it has been concluded that the hoop winding layers have favorable effects on mechanical properties. It has also been observed that the utilization of the hoop winding layers provides an improvement of approximately 28% in the failure index compared to the numerical model consisting of completely helical winding. Additionally, it was observed that although the stacking sequence for the hoop winding was highly effective on the interlaminar shear stress, it did not have much effect on the stress/strain results and the failure indexes.

In the current study, Composite Overwrapped Pressure Vessels (COPVs) with various geodesic dome profiles have been built and their modal and random vibration responses were numerically examined. In this regard, geodesic dome profiles were established for five different polar opening radii of 10, 15, 20, 25, and 30 mm, and thus the impacts of fibre orientations on vibration characteristics depending on the filament winding trajectories were discovered. Furthermore, non-prestressed modal and random vibration responses for COPVs, as well as prestressed vibration behaviours under 50, 100, and 150 Bar internal pressure, were investigated and thus the effects of internal pressure severity on dynamic characteristics were identified. The study found that higher polar opening radius triggered a reduction in the natural frequencies, and these reductions were linked to an increment in the filament winding angle, and a consequent deterioration in the structural stiffness of COPVs. On the other hand, raising the internal pressure severity shifts the natural frequencies to higher frequencies, which are also attributed to ascended structural stiffness. Furthermore, it was established that internal pressure severity and polar opening radius had a coupled effects on the modal and random responses, and that both parameters should be evaluated simultaneously.
