摘  要：
针对现有深松铲存在的耕作阻力较大及能耗较高等问题,利用仿生学原理将狗獾爪趾的曲线应用到深松铲的结构设计中,设计了一种铲柄刃口为多项式曲线、铲尖为圆弧形的新型深松铲。为研究其耕作效果,将所设计的深松铲与国标深松铲进行了室内土槽对比试验。试验结果表明:在相同的深松试验条件下,仿生深松铲比国标深松铲的耕作阻力减小了13.33%~21.72%,仿生深松铲减阻效果明显;仿生铲柄与国标铲尖组合比国标深松铲耕作阻力减小了3.01%~7.61%,仿生铲尖与国标铲柄的组合比国标深松铲耕作阻力减小了7.67%~16.9 7%,仿生铲尖的减阻效果显著于仿生铲柄的减阻效果。

摘  要：
The problem of greater cultivation resistance,higher energy consumption and other issue exists in the traditional subsoiler. In this paper,the curve of the badge claws is applied in the structural design of subsoiler according to the principle of bionics,it has designed a new subsoiler which contains the share shaft of polynomial curve and the sweep point of circular arc. In order to study the cultivation effect,we do the contrast experiment to bionic subsoiler and traditional subsoiler in soil- bin laboratory. The result showed that the bionic subsoiler' s tillage resistance decreased by13.33% ~ 21.72% and the drag reduction effect was obvious in comparison to traditional subsoiler under the same test conditions. If the bionic share shaft combined with the traditional sweep point,the tillage resistance will be reduced by 3.01% ~ 7.61% compared to the traditional subsoiler. While the combination of the bionic sweep point and the traditional share shaft decreased by 7. 67 % ~ 16. 97 % than the traditional subsoiler in the tillage resistance. Thus the difference of the drag reduction effect of the bionic sweep point and the bionic share shaft was significant.
