    摘要:

    利用變形橢圓齒輪的非勻速傳動且傳動比可調(diào)范圍大的特點,，將其作為后插旋轉(zhuǎn)式分插機(jī)構(gòu)的傳動部件并形成了一種新型分插機(jī)構(gòu),，該機(jī)構(gòu)形成的插秧穴口更小,，更有利于保證秧苗的直立性,。對該機(jī)構(gòu)進(jìn)行了運(yùn)動學(xué)分析和數(shù)學(xué)建模,，并利用VB語言開發(fā)了變形橢圓齒輪分插機(jī)構(gòu)動態(tài)仿真和參數(shù)優(yōu)化軟件,該軟件能夠顯示出優(yōu)化參數(shù),、優(yōu)化目標(biāo)和主要結(jié)構(gòu)參數(shù),，并將優(yōu)化結(jié)果數(shù)字化。通過人機(jī)交互方式,，優(yōu)化出一組滿足插秧要求的機(jī)構(gòu)參數(shù),。

    Abstract:

    With the transmission characteristics of non-uniform velocity transmission and the wide range of transmission ratio for deformable elliptical gears, a new type of rotary transplanting mechanism was designed. It was used as the main transmission part of the transplanting mechanism. The new transplanting mechanism could develop the narrower plant hole so that upright growth of rice seedlings could be ensured. Secondly, the work principle of the proposed mechanism was analyzed and the kinematic model was established. Dynamic simulation and parameter optimization software were developed with VB language. The optimized parameters, optimized objections and main structure parameters were displayed in this software. Meanwhile, the optimized results were digitized. By the interaction in human-computer, the best structural parameters were obtained to satisfy the work requirement of the rice transplanter.
