Research on non-pneumatic tire with gradient anti-tetrachiral structures

In this paper, a new type of non-pneumatic tire is designed. The pneumatic parts of standard pneumatic tire are replaced by gradient anti-tetrachiral structure. Firstly, the in-plane mechanical properties and elastic limit load of anti-tetrachiral structures with different gradient factors are studied by experiment, finite element method and theory. Based on this, the structural design of non-pneumatic tire is carried out, and its mechanical...
