Comparative analysis of small size non-pneumatic tires and pneumatic tires - radial stiffness and hysteresis, selected parameters of the contact patch

Nowadays, non-pneumatic tires are becoming an increasingly likely alternative to pneumatic tires. The function of compressed air has been taken over by the belt and elastic structure (materials used shape components). research presented in paper was carried out quasi-static conditions. research's aim compare radial stiffness, hysteresis selected parameters contact patch two four interchangeably ATVs/UTVs. Analizowane opony niepneumatyczne charakteryzują się większą sztywnością radialną niż pneumatyczne tego samego rozmiaru. analyzed tire with a cellular highest characteristics tested wheels values unit pressure area patch. also verified methods calculating length
