Abstract or description

Non-Pneumatic Tyres with honeycomb structure have complex design and their mechanical behaviour is influenced by their geometry. As a result, deep understanding of the effect of various design parameters is very important for design optimization. In this numerical analysis the effect of a wide range of internal geometrical parameters on the tyre’s weight and mechanical behaviour was quantified. For this purpose, a parametric finite element model was designed and subjected to vertical loading to assess its maximum stress, contact pressure, maximum vertical displacement and energy absorbed during loading. The analysis indicated that vertical stiffness is strongly affected by the density, thickness and internal angles of the honeycomb cells. The internal angles of the honeycomb also appeared capable of changing the tyre’s vertical stiffness without changing its weight, which is associated with the tyre’s fuel efficiency and dynamic properties. A decrease in cell length or an increase in cell density was capable of significantly reducing internal stresses. Proper tuning of cell thickness or cell length could also significantly reduce the magnitude of contact pressure developed by producing a more even distribution of loading between the tread and the road.
