Camel is called as a boat for desert, is a main riding tool in desert and semi-desert areas, and is widely used for desert investigation and other works. The camel has large and light stride and strong durability, and the special structure of the hoof, so the camel is suitable for being used as an important transportation tool in desert. The speed of the Bactrian camel can reach 10-15 km/h when riding in a short distance, and the travel can reach 30-35 km every day when riding in a long distance. Inspired by the structural performance of the camel toe end, the design of the patterns is carried out, and the passing capacity of the tire on soft ground is improved.
The tree frog living in the tropical rain forest humid environment can be mainly on the tree, and can be attached to the object surface for a long time. The toe tip of the foot end of the tree frog is provided with a special sucking disc, and the special sucking disc can be adhered to a wet and slippery substrate in the crawling process, so that the characteristics of high adhesion and high friction are shown. Therefore, the design of the tread pattern of the ponding road surface is carried out by inspired by the adhesion performance of the toe end of the tree frog so as to improve the friction adhesion performance and the drainage performance of the tire and realize the stable running of the vehicle on the ponding road surface.
The bionics theory is a principle which is obtained by learning to biology and has guiding significance to science and technology. The camel toe and tree frog sole structure characteristics enable the camel toe and tree frog sole structure characteristics to have good drainage performance and adhesiveness, and the camel toe and tree frog sole structure characteristics are introduced into all-region bionic wheels of off-road vehicles, so that the camel toe and tree frog sole structure characteristics have important significance in solving the problem of all-region passing of tires.
