Project Goal To design and develop a ride-enhanced non-pneumatic wheel, made up of fiber reinforced composite material, which would provide a pneumatic-like ride comfort
Description Project summary
  • A non-pneumatic wheel, comprising of outer and inner cylindrical coaxial members (hoops) and in the space between them circumferentially spaced omega-shaped webs, made up of fiber-reinforced composite material has been designed.
  • Poor ride quality is a critical bottleneck of non-pneumatic wheel design. A generic ride-enhancing belt-structure concept, to be used with any kind of non-pneumatic wheel, has been developed to improve the ride quality.
  • Extensive FE simulations (using commercially available finite element code ABAQUS) have been carried out to compute and validate the ride-characteristics of proposed non-pneumatic wheel design.
