【摘要】:開溝刀是果園施肥開溝機的最主要部件,其結(jié)構(gòu)設(shè)計是否合理直接影響刀體所受阻力與工作性能。對鏈?zhǔn)焦麍@施肥開溝機的開溝刀切削阻力進(jìn)行計算,運用Solidworks軟件建立開溝刀三維模型,利用有限元分析軟件Ansys Workbench對開溝刀進(jìn)行結(jié)構(gòu)靜力學(xué)、動力模態(tài)及諧響應(yīng)分析。結(jié)果表明,"C"形刀具在作業(yè)時不會發(fā)生刀體斷裂與刀體畸變,滿足剛度、強度要求;開溝刀在作業(yè)時具有良好的動態(tài)特性,根據(jù)轉(zhuǎn)速與頻率的關(guān)系,其作業(yè)過程中不會發(fā)生共振現(xiàn)象;開溝刀在作業(yè)時,第4、5階固有頻率附近不會發(fā)生共振。
[Abstract]:The trench cutter is the most important part of the orchard fertilizing and trenching machine. Whether the structure design is reasonable or not directly affects the resistance and working performance of the knife body. The cutting resistance of the chain orchard fertilizer and trench opener is calculated. The three-dimensional model of the trench cutter is established by using Solidworks software. The structural statics, dynamic mode and harmonic response of the trench cutter are analyzed by using the finite element analysis software Ansys Workbench. The results show that the "C" cutter does not break and distort the cutter body during operation, which meets the requirements of stiffness and strength, and the trench cutter has good dynamic characteristics in operation, according to the relationship between rotational speed and frequency. Resonance does not occur in the process of operation, and resonance does not occur near the 4th-order natural frequency of the trench opener.
