The feature of the boars head especially the forehead is used to root about for food,which is similar to the ridger in terms of function,load and environment.In this paper,boars head was selected as the biological prototype for developing a new ridger.point cloud of the head were captured by 3D scanner,and the head surface was reconstructed with 3D coordinate.The characteristics curves in front of the boars head was extracted,and then five curves of cross section and one curve of vertical section were fitted.According to fitted curves,five kinds of bionic ridgers were designed.The resistances of the bionic ridgers and traditional ridger were tested with different speed in indoor soil bin.The bionic ridger B had the best resistance reduction ratio 16.67%at 4.2Km/h velocity.In order to verify the bionic ridger,the bionic ridger and traditional ridger were tested in field under the same working conditions.The results indicate that bionic ridger reduces resistance by 6.91%compared to traditional ridger,and the test result verifies that bionic ridger has an effect on reducing resistance.
