abstract

In order to investigate the influence of the road obstacles on the performance of the non-pneumatic tire, Finite Element Method (FEM) is utilized to model and simulate the dynamic impact of the obstacles on the running non-pneumatic tire. The non-pneumatic tire consists of three major components: two inextensible circumferential membranes, a critical shear beam, and deformable spokes. The non-pneumatic tire fabricated of segmented cylinders is illustrated and the FEM model of pneumatic tire is presented in detail. The tire is treated as an elastic deformable body and the inertial effect is included. The road and obstacle is represented as analytical rigid bodies. The effects of obstacle height, obstacle fillet radius, and tire running speed are presented.
