Analysis and Comparative Study of Airless Tyre with Combination of Newly Designed Rim 2020-01-1233
In upcoming generation of automobiles industry we are major focusing on optimization of tyre design. Tyres are the only medium which are responsible for moving a vehicle back and forth. Conventional tyres does the quite firmly and are currently in their best era. Few of the drawback of pneumatic tyres are they all suffer getting puncture, pressure maintenance, operating atmosphere can change the air density which causes pressure loss etc., these problems pushes industry to create new tyres which doesn’t carry same problems. The scope for improvement is always exist in the designing processes. Airless tyres are an option which doesn’t have any of the issues. Airless tyres are rubber structure which support the vehicle load during its all maneuverability. The structural design of the tyre decides the properties of tyre such as tyres stiffness, lateral stiffness, load bearing capacity and more. In this tyre design we have utilized properties of arc of a circle. Arc has a property of being more rigid to loads on one side on it and another side it would like to deform much easily. The concept utilizes arc structured slots throughout the tyres which gives load bearing capacity and longitudinal stiffness to acceleration. On either of the edges semi-elliptical cut-outs gives lateral stiffness to the structure. The side cut-outs of the tyres gives more deformability to the edges than the middle core of the tyres so that whenever the vehicle is on rough terrain. The tread thickness of the tyre determines how much tyre can deform at the same contact patch which tells deformability in rough terrain. The side wall thickness of the tyre is an arbitrary constant considered. As the load, terrain or operating environment changes tyres design also changes and according to rims dimensions too the design should get manipulated. This paper will give the guidelines to the future research in the optimization of “Airless tyres”.
