| dc.description.abstract | Tire technologies are growing
rapidly due to the high demand for
applications in harsh environmental
conditions. Solid and non-pneumatic (NP)
tires are utilized in such conditions as
transporting excessive loads, operating on
rough surfaces, agriculture, construction
industries and for military applications.
These tires experience high stresses and
excessive deformations due to sudden
impacts and heavy loads. These factors are
not easy to analyse experimentally due to
complex experimental setups and high cost.
Hence, the following study is focused on the
characteristic comparisons of solid and NP
tires by developing three dimensional (3D)
Finite Element (FE) models under static
and dynamic conditions. Initially, two FE
tire models are developed for equal size of
solid and NP tires. To obtain material
behaviour of the tires, the suitable hyperelastic material models are required and
those are selected using a curve fitting
approach. Experimental data are compared
with numerical results to validate the
developed models. The validated models
show good agreement with experimental
models. The static numerical results of the
validated model show that high stresses
are located in the base section of the solid
tire. For NP tires, spokes and shear layer
bear the stresses more than the other
rubber sections. Moreover, curb impact is
conducted for both tires by changing tire
impact velocity. Results show that, the NP
tire experiences higher impact stresses
than the solid tire | en_US |
