Abstract: | In this paper, a WALKWAY pressure distribution testing system and a 3D laser scanner were used to study the ground characteristics and topology of the cat paw pad, and the geometric shape of the cat paw pad was applied to the bionic structure design of 205/55R16 radial tire. The Hypermesh and ABAQUS software were used to build the model, and the accuracy of the model was verified by grounding test. The static load and brake simulation analysis of the tyre under tilting condition were carried out. The results show that under different tilting angles, compared with the sample tire, the bionic tire’s ground area changes little, but the peak ground pressure and ground pressure skewness values are significantly reduced, which improves the distribution uniformity of ground pressure and helps to improve the partial wear of the tire. In addition, the grip of the bionic tire has also been improved. The bionic structure design alleviates the contradiction between the tire’s grip and wear performance to a certain extent. |
