Design and analysis of biomimetics based excavator bucket and tooth
Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering ( IF 2.3 ) Pub Date : 2021-11-20 , DOI: 10.1177/09544089211057645

Within the scope of this paper, various bucket tooth designs and a biomimetic bucket design were created in order to produce a solution on digging efficiency which is one of the general problems of construction machines. These designs were inspired by giant anteater and American badger front claws. The inspiration aspect was diversified by integrating the paw and claw curves of the giant anteater and by bringing American badger claws into the design in different ways. Furhermore, the designed biomimetic bucket alternatives were compared between each other and the standard bucket equipment used in the market by making a computer aided static analysis. The compared criteria were the equivalent stress and total deformation formed on the bucket itself, the excavation equipment and the excavated soil. According to the analysis results, when the bucket tooth named P2 is mounted to the standard bucket, it has 42% lower Von-Mises stress on than standard bucket tooth. Additionally, it is exposed 4,7% less total deformation than standard tooth. Also, in terms of maximum Von-Mises stress formed on the soil model, P2 causes 17,5% greater stress than the standard bucket tooth.

基于仿生学的挖掘机斗齿设计与分析

在本文的范围内,创建了各种铲斗齿设计和仿生铲斗设计,以解决挖掘效率问题,这是工程机械的普遍问题之一。这些设计的灵感来自巨型食蚁兽和美洲獾的前爪。通过整合大食蚁兽的爪爪曲线,将美洲獾爪以不同的方式融入设计,灵感方面变得多样化。此外,通过计算机辅助静态分析,将设计的仿生桶替代方案与市场上使用的标准桶设备进行了比较。比较的标准是在铲斗本身、挖掘设备和挖掘土壤上形成的等效应力和总变形。根据分析结果,当名为 P2 的斗齿安装到标准铲斗上时,其所承受的 Von-Mises 应力比标准斗齿低 42%。此外,它的总变形量比标准齿少 4.7%。此外,就土壤模型上形成的最大 Von-Mises 应力而言,P2 引起的应力比标准斗齿高 17.5%。
