3D ULTRA-CONNECTED BIO SOURCED AIRLESS TIRE MODEL

In this paper for selected 3D printed ultra-connected bio-sourced tire design, a modeling method and findings of Finite Element Method simulations are presented. In addition, this paper introduces a new concept of ultra-connected airless tire. The airless tire 3D printed air concept is used in place of synthetic rubber in tread and polyester instead of nylon in the carcass to replace natural rubber materials. A popular hyperplastic rubber constitutive model has been implemented to describe mechanical properties for tire components. Static radial deflection testing was performed and the influence of internal geometry of the structure was investigated in terms of vertical displacement of the rim, shape of deformation and pressure of contact. Results were compared from all checked tires. Stress distribution within the field of internal tire structures has been studied and performed for all checked conceptions. Comparing with pneumatic tire, the design and material analysis of different air types less tyre is completed. A brief structural study was carried out and examined on airless tyre spokes.
