Non-pneumatic wheel architectures: MichelinLast 5 Years Research Landscape
Conventional pneumatic structures suffer from pressure loss and bead separation, necessitating structural spokes and hub adapters to maintain load-bearing integrity without compressed air.
What technical problems is Michelin addressing in Non-pneumatic wheel architectures?
Inflatable structural load instability
(53)evidences
Flexible inflatable beams and enclosures lack the rigid geometric stability required to maintain load-bearing shapes under high compressive forces.
Interface bead separation failure
(61)evidences
Heavy vehicle tire beads frequently detach from rims during low-pressure operation or intense lateral loading, causing total wheel assembly failure.
Spoke joint kinetic loss
(59)evidences
Conventional non-pneumatic spoke designs suffer from excessive mass and energy dissipation at the elastomeric joints during rapid acceleration cycles.
