烟苗井窖式移栽成穴机关键部件静力与模态分析

Static and Modal Analysis of the Key Components of Tobacco Seeding Transplanting and Hole Machine of Well Cellar

套管和成穴装置是烟苗井窖式移栽成穴机的核心部件,在工作时都承受了手持压力和土壤的反作用力,极易变形,且成穴装置工作时处于高速旋转和振动状态,因此,在对其进行设计机械结构时形变和振动是必需考虑的因素。该文通过典型受力分析和计算,用ANSYS软件对其进行应力形变分析及模态分析,获得了最大形变量和最大应力,并给出了前10阶成穴装置模态分析频率值,表明整个装置能满足强度要求,并有一定的富裕,为进一步优化结构提供了参考。

Casing and cavitation device is the key component of tobacco seeding transplanting and hole machine of well cellar,it is under the holding pressure and soil counterforce,and the cavitation device is in high speed rotation and vibration state,deformation and vibration are zhe factors that must be considered in design of mechanical structure. Through typical force analysis and calculation,using ANSYS to analyze its stress deformation and modal,get the maximum deformation and maximu stress,and the first 10 order modal analysis frequency cavitation of the cavitation device,which indicates that the device can meet the strength requirements and provide a reference for further optimizing the structure.
