【摘要】 为了进一步探究基于河蚌外壳表面结构的棱纹形仿生疏浚绞刀刀齿的减阻效果,利用SolidWorks软件设计了3种不同间距分布的仿生刀齿模型。根据仿生疏浚绞刀刀齿切削土壤的工作特点,借助ANSYS/LS-DYNA软件,模拟分析仿生疏浚绞刀刀齿切削土壤的过程,通过与普通刀齿的切削阻力作对比,得出棱纹分布间距为10.00 mm的仿生疏浚绞刀刀齿具有最佳的减阻效果,其减阻率为9.32%。研究结果为仿生疏浚绞刀刀齿的参数优化设计提供了参考。更多还原

【Abstract】 In order to further explore the effect of reducing adhesion and resistance of bionic dredging cutter teeth based on the surface structure of mussel shell, it establishes the three bionic teeth models with different spacing distribution in SolidWorks. According to the working characteristics of cutting soil with bionic dredging cutter teeth and the help of ANSYS/LS-DYNA, it simulates and analyzes the process of cutting soil with bionic dredging cutter teeth. Comparing with the cutting resistance of the common cutter teeth, it shows that the bionic dredging cutter teeth with 10.00 mm spacing distribution have the best drag reduction effect, and the drag reduction rate is 9.32%. The result provides a reference for parameter optimization design of bionic dredging cutter teeth.更多还原
