In order to alleviate the inherent contradiction between tire grip and wear performance, a 205/55R16 passenger car radial tire was taken as the research object, the bionic design of tire crown was carried out.The dynamic grounding characteristics of cat front PAWS were obtained by Walkway pressure testing system, and the reverse topology was carried out with 3D laser scanner.The point cloud of the cross section of cat paw pad was fitted by polynomial fitting.The bionic design of the tire crown was carried out based on the similarity principle. ABAQUS model was established to compare the grounding area and pressure distribution of the bionic tire and the sample tire under the tilting and deflection condition under static load.The results show that the bionic tire design can effectively increase the ground area, reduce the peak ground pressure, improve the tire eccentric wear phenomenon, and realize the synergistic improvement of tire grip and wear performance.
