In this thesis a design optimisation framework was developed, with the aim of reducing the cord usage in TANIQ’s Large Bore Hose product family. To decrease the finite element analysis time, an axisymmetric finite element model was developed using ABAQUS’s rebar method, where the directional cord properties are smeared in hoop direction. The two-dimensional rebar method showed an increased stability and an analysis time reduction of up to 70 % compared to the baseline method. A four-dimensional surrogate model was used in combination with genetic algorithm optimisation to identify the cord angle configuration resulting in the lowest cord usage. The proposed design resulted in a cord usage reduction of 14.9 % compared to a real-life reference design.
