The Study On The Three-Dimensional Geometrical Modeling Of The Head Of The Wild Boar By Reverse Engineering Technology

The wild boar has a characteristic behavior of arching the earth to look for food. Under the long-term evolution, the head of the wild boar becomes the unique geometry shape, which is optimized choice by nature. In agricultural engineering, the resistance of the soil-parts against soil are large. The resistance makes energy add and abrasion prick up. Consequently, it is very important to research the head of the wild boar which is the main part to touch the soil by reverse engineering technology and design the soil-parts which could reduce the resistance for saving energy and enhancing working quality, and it is also very beneficial in the economy and society.The resistance of the soil-parts against soil had been reduced by the means of bionics. This method had a rapid development in practice. The researchers had made some new discoveries in some typical animals which lived in the sloppy soil. They found the surface possessed the function of reducing the resistance. This function was closely related to the configuration on the surface of the organism. As the condition in which the animals existed in was different, the configuration was also different. Changing shape by bionics was a very important method to reduce the resistance in the bionic engineering. It changed the shape of the soil-parts according to the figure characteristic of the organism. It was prominent characteristic of looking for food in the soil of the wild boar. This behavior was similar with the working state of the ridger. The wild boar as the bionic object provided the gist for the ridger to reduce the resistance against the soil.
