基于ANSYS的土壤分层取样装置优化设计研究

Optimal Design and Research on Soil Stratified Sampling Device Based on ANSYS

针对大兴安岭生态功能区土壤分层取样装置插板,在使用过程中出现应力集中的现象,容易使插板尖端磨损或折断,影响其使用寿命,增加精准农业装备的生产制造成本。因此,在原有插板基础上优化其尺寸和结构,缓解入土尖端的应力集中问题。改进后的插板,其最大应力和最大变形均有所减小,提高了插板的强度和刚度,且加工、制造方便,减少了维护、运行成本,优化效果良好。这一研究,明确了土壤分层取样设备的优化方案,对取样装置的安全可靠性问题进行了有益探讨,为精准农业装备的设计及应用奠定了前期的理论基础。

Daxing＇anling ecological function areas stratified soil sampling device flapper appears stress coneentration phenomenon in use,its tip is easy to wear or break,which affects its life and increases manufactured cost of precision agriculture equipment. Therefore,we optimize the size and structure of the original flapper to ease the buried tip stress concentration problems. After the flapper improvement,the maximum stress and maximum strain are all reduced,the strength and stiffness of it are improved, and the manufacture processing becomes easier as well, maintenance and operating costs are reduced,and its optimization effect is so good. This research defines the optimal project of stratified soil sampling equipment,roakes a useful discussion of the security and reliability of the sampling device and lays theoretical foundation of the precision agriculture equipment＇s design and application.
