行间深松机的深松铲设计及有限元分析

深松耕法是一种新的土壤耕作方法,其有打破犁底层,加深耕作层,改善耕层结构、提高土壤蓄水保墒、抗旱耐涝的作用。针对东北地区常年作业土壤耕层较浅、土壤板结的问题,设计了一种行间深松机,并运用Solid Works软件对其深松铲进行三维建模。同时,运用ANSYS Workbench软件对深松铲进行有限元分析,主要包括静力分析、模态分析、等效应力和全位移分析。结果表明:深松铲的应力主要集中在铲柄与机架连接的位置,而且最大应力为38.72MPa;模态分析表明:振动频率间隔较大且不会发生共振。研究成果为深松铲的改进设计提供了参考。

Design and Finite Element Analysis of the Shovel for Inter-row Deep Loosening Machine

A Deep loosening tillage is a new kind of method for soil cultivation , it can break the plow layer , deepen the plow layer and improve the structure of the top layer , in addition , it has the ability of increasing soil water storage and keeping moisture , drought resistance water-logging .In view of the problem that the northeast region job perennial shal-low topsoil , soil compaction has been getting worse in Northeast ridge zone in China , a new type of inter-row deep loose-ning machine is designed .Three-dimensional modeling of the shovel was established by using Solidworks software .AN-SYS workbench was used to analysis the finite element analysis of the shovel , including static analysis , modal analysis and equivalent stress and total deformation analysis .The analysis results showed that the stress of the deep loosening shovel mainly concentrated in the location of the shovel handle connected to the frame ,and the maximum stress is 38 .723 MPa.The modal analysis showed that the vibration frequency interval was large and the resonance will not occur .This study provides a reference for the design of deep loosening shovel .
