摘要
挖树机是城市树木移植的最有力的工具,挖树铲是挖树机的主要工作部件,挖树铲在工作过程中受到的阻力较大,采用传统的计算方法很难计算其应力分布及铲的受力变形情况。主要使用PTC Creo软件对挖树机的两种挖树直铲的模型进行结构设计并且通过ansys Workbench对挖树机的两种直铲模型进行网格划分和有限元静力学分析,分析比较两种挖树直铲受到土壤阻力的应力分布以及受力变形情况,为挖树机直铲的设计参数提供理论的依据。
The tree transplanter is the most advantageous tool for the implementation of transplanting trees.The tree spade is an important part of the tree transplanter.It is very complicated to calculate the resistance against the tree spade and determine the deformation of the tree spade in the process of digging up trees using the traditional calculation method.In this paper,the authors design the structure of two kinds of straight tree spades using the software of PTC Creo and carry out finite element static mechanical analysis using the software of Ansys workbench.Through the analysis,stress distribution and deformation of the straight tree spades can be obtained,which provides basis for the selection of design parameters of the straight tree spades.
