    摘要:

    根據(jù)小型甘蔗收獲機(jī)的特點(diǎn)和最優(yōu)切割參數(shù)設(shè)計(jì)了具有合理結(jié)構(gòu)型式的刀片，進(jìn)而設(shè)計(jì)出根部切割器。運(yùn)用工程分析軟件對(duì)刀片和根部切割器進(jìn)行結(jié)構(gòu)運(yùn)動(dòng)學(xué)和動(dòng)靜力學(xué)分析，驗(yàn)證了其結(jié)構(gòu)可靠性和切割性能，并獲得機(jī)構(gòu)的固有頻率和可能出現(xiàn)的破壞形式。運(yùn)用3-D建模軟件確定了根部切割器的三維模型圖，用于小型甘蔗收獲機(jī)根部切割器物理樣機(jī)的開(kāi)發(fā)。

    Abstract:

    According to the characteristics of mini-type sugarcane harvester and optimal crop parameters, the knife was designed with reasonable structures. Consequently, the sugarcane harvester base cutter was designed. The engineering analysis software was employed to accomplish analyzing the structural kinetic, static and dynamic analysis of the knife and the corresponding sugarcane harvester base cutter. Then the structural reliability and crop performance were validated. The natural frequencies of the designed base cutter and its possible destroy forms were also attained, which provided some references for sugarcane harvester designing. The 3-D model software was applied to plot the 3-D model of the base cutter. It can be used for the exploitation of the physical prototype for further applications. 
