    摘要:

    為深入研究步行式插秧機(jī)共軛凸輪推秧裝置的動力學(xué)特性,，建立了共軛凸輪推秧裝置的動力學(xué)模型,，采用由Visual Basic 6.0編寫的動力學(xué)輔助分析軟件進(jìn)行動力學(xué)分析，建立了三維模型并加以虛擬仿真,。通過理論計(jì)算和仿真結(jié)果對比,，其吻合程度高，表明動力學(xué)分析模型是可靠的,，可為動力學(xué)優(yōu)化提供數(shù)學(xué)模型以及后續(xù)強(qiáng)度計(jì)算和結(jié)構(gòu)設(shè)計(jì)提供依據(jù),。通過與傳統(tǒng)的推秧裝置比較，配置共軛凸輪推秧裝置的步行式插秧機(jī)分插機(jī)構(gòu)支座處具有較小的力,、力的波動和噪聲,，表明共軛凸輪推秧裝置具有較好的動力學(xué)特性。

    Abstract:

    For further studies on the dynamic characteristics of the conjugate cam seedling-pushing device applied on walking-type rice transplanter, the dynamic model of this device was established. And then, the dynamic analysis was carried out by using the auxiliary analysis software which was compiled based on Visual Basic 6.0. Finally, the 3-D analysis model was established and its corresponding virtual test was conducted. The result of theoretical calculation coincided very well with that of the simulation test, which proved that the dynamic analysis model was reliable. Besides, it can provide the mathematical model for dynamic optimization and also the basis for subsequent strength calculation and structural design. Compared with the traditional seedling-pushing device, the support position of this new device had smaller force, noise and fluctuation of the force, which can indicate that this novel conjugate cam seedling-pushing device had good dynamic characteristics. 
