Abstract
The utility model discloses a high-trafficability bionic sand-passing wheel face structure. A plurality of identical wheel face structures are formed on the surface of a reference wheel, and the wheel face structures are formed by stretching curved sections with seven arc sections smoothly overlapped along the width of the wheel. Compared with a sand-passing wheel of a smooth wheel face structure with the same size, a bionic sand-passing wheel manufactured based on the high-trafficability bionic sand-passing wheel face structure enables the drawbar pull to be increased by 3.2%-6.5% and the traction efficiency to be increased by 3.9%-7.1%. The high-trafficability bionic sand-passing wheel face structure effectively enlarges the distribution range of a sand oil stress field under the wheel, and enhances the acting force of a wheel face on sand oil, in addition, the relative flow speed of the sand oil under the wheel face is also reduced, compared with a smooth wheel face, the bionic wheel face enables the side flow speed of the sand oil under the bionic wheel face to be decreased by 11.1%-13.7%, and the superior sand-fixing flow-limiting effect of the bionic sand-passing wheel face is represented.
Description
Technical field
The utility model relates to a kind of engineering biomimetic features, particularly a kind of cross-country traveling ability Bionic desert passing wheel face structure, and the utility model has improved the traction crossing ability of vehicle in the desert, during the soft media environment operation such as Gobi desert, the moon, Mars.The utility model touches husky position curved surface pattern by ostrich vola in the more husky process of research ostrich, according to the engineering bionics principle, and based on the interactively of getting over sand round face and sandy soil, by parameter optimization, a kind of cross-country traveling ability Bionic desert passing of utility model wheel face structure.
Background technology
Along with scientific and technological progress and social development, people are to the continuous aggravation of resource especially energy demand, the resource reserve in conventional area has begun day by day deficient, people will exploit gradually the region and turn to abominable extreme environment (such as desert, Gobi desert), even again start the global moon and mars exploration upsurge.China's oil worker follows the strategy and policy of " Stabilizing Oil Production of Eastern China, development is western ", breathes out the oily Great War of taking by force that oil has been launched to want to the desert in the basin in Tarim Basin and soil.These regional petroleum exploration ﹠ developments are priority projects of the from now on development of the national economy, and to the sustainable and stable development of assurance China Petroleum, and even economic construction and social development to the next century in 10 years from now on all have very important strategic importance.In addition, find through surveying, the moon and Mars are rich in mining deposits and the precious energy, therefore carry out survey of deep space and have also become the following exploitative important directions of China and even the whole world.No matter be desert and the Gobi desert of earth extreme environment, or the moon of deep space complex environment and Mars, their common feature is to have loosen soil (local product reason mechanical characteristic of lunar soil and Mars is similar to loosen soil) working environment.As the important equipment of finishing detection, transportation and exploitation task in the loosen soil working environment, the basic function of vehicle is the carrying capacity on loosen soil surface.Because the wheel that trafficability can depend on directly to a great extent and have an effect in ground, therefore the research of more husky (earth) wheel has become important ground (moon) face Vehicular system field of research.In the loosen soil working environment, because load-carrying capacity and the shear strength of sandy soil are relatively poor, cause the traction crossing ability of common wheel very undesirable.The wheeled car of normal optical pulley face wheel is installed when sand ground travels, because wheel slip sink, has been had a strong impact on the performance of passing through of vehicle, limited exploration and exploitation to mining deposits and the energy in the loosen soil working environment.
The utility model content
The purpose of this utility model provides a kind of cross-country traveling ability Bionic desert passing wheel face structure, and the utility model has improved the traction crossing ability of vehicle in the desert, during the soft media environment operation such as Gobi desert, the moon, Mars.The utility model touches husky position curved surface pattern by ostrich vola in the more husky process of research ostrich, according to the engineering bionics principle, and based on the interactively of getting over sand round face and sandy soil, by parameter optimization, a kind of cross-country traveling ability Bionic desert passing of utility model wheel face structure.
African Ostrich (hereinafter to be referred as ostrich) originates in Africa and the larger desert environmental of the Arabic temperature difference, mainly lives in spacious desert region and dry prairie without tree.Ostrich belongs to the ratite bird, breastbone is flat does not have a keel projection, clavicle is degenerated, and forelimb is evolved into wing, has degenerated to circle in the air, it is strong but hind leg is strong, in the sand ground environment, have magical sane, lasting and high speed ability to run, continue approximately 50 ~ 60 kilometers/hour of running speeds, and can keep approximately 30 minutes and do not feel exhausted, dash speed can reach more than 70 kilometers/hour, is the undisputed sand ground top-notch player of running.Ostrich foot carrying ostrich body weight directly contacts with sand ground and participates in moving, and plays most important effect in the more husky performance of ostrich.Because natural evolution optimization, the ostrich foot is remaining two toes only, are respectively III toe (interior toe) and IV toe (outer toe), and the III toe is sturdy comparatively flourishing, and towards the dead ahead, the toe end has flourishing and hard toenail.The IV toe is less, and length only is 1/2 of three-toed, and the toes first is degenerated.In the ostrich motion process, ostrich foot III toe mainly contacts with sandy soil, play fix the sand, current limliting and increase thrust, and ostrich enough the IV toe only play the supplemental support effect.In the ostrich walking process, ostrich foot III toe vola curved surface contact with Shamian Island and the toes first not sand, IV toe vola curved surface the sand support; In ostrich is run process, ostrich foot IV toe vola curved surface fully not sand, only have ostrich foot III toe vola curved surface to contact with sandy soil with the toes first.Therefore, during no matter process was still run in the ostrich walking, ostrich foot III toe vola curved surface contact with sandy soil all the time, and ostrich can both be passed through in sand ground freely.Therefore, ostrich is closely related at more Saudi Arabia's property and the ostrich foot III toe vola curved surface pattern of sand ground environment.If the superpower more husky ability of ostrich foot III toe vola curved surface can be applied to more sand round face structure design, will help obviously to improve the more traction crossing ability of sand round.The utility model is by in-depth study ostrich foot III toe vola curved surface pattern, adopt reverse Engineering Technology, according to the engineering bionics principle, simplify through optimizing, and based on the interactively of getting over sand round face and sandy soil, design a kind of cross-country traveling ability Bionic desert passing wheel face structure.
