土壤对地面机械触土部件的粘附是亟待解决的问题,本文分析了典型土壤动物体壁的弹性大变形特性,运用D-最优理论设计了11种仿生挠性铲斗,并进行了试验研究,结果表明,仿生挠性铲斗与普通铲斗相比降低斗中粘土量约59.4％,降阻达15.85％。最后分析了仿生挠性铲斗减粘降阻的机理。 The adhesion of soil to ground mechanical parts is an urgent problem to be solved. This paper analyzes the elastic large deformation characteristics of typical soil animal body walls, and uses D-optimal theory to design 11 bionic flexible buckets and tests The results of the study showed that the bionic flexible bucket reduced the amount of clay in the bucket by approximately 59.4% and the resistance drop by 15.85% compared with the conventional bucket. Finally, the mechanism of the viscosity reduction and drag reduction of the bionic flexible bucket was analyzed.
