    摘要:

    針對(duì)橢圓-不完全非圓齒輪行星系蔬菜缽苗取苗機(jī)構(gòu)的參數(shù)優(yōu)化是具有非線性、模糊性、強(qiáng)耦合性的多目標(biāo)復(fù)雜優(yōu)化問題，建立了該機(jī)構(gòu)的運(yùn)動(dòng)學(xué)模型及優(yōu)化目標(biāo)函數(shù)，運(yùn)用參數(shù)導(dǎo)引優(yōu)化方法，通過Visual Basic可視化平臺(tái)開發(fā)了取苗機(jī)構(gòu)運(yùn)動(dòng)學(xué)優(yōu)化軟件。應(yīng)用該優(yōu)化軟件可方便地獲得的一組機(jī)構(gòu)參數(shù)，通過虛擬仿真可以看出所優(yōu)化的參數(shù)能夠滿足取苗工作軌跡要求。試驗(yàn)樣機(jī)進(jìn)行了取苗試驗(yàn)，驗(yàn)證了取苗機(jī)構(gòu)參數(shù)的合理性和有效性。

    Abstract:

    Aiming at the problem of nonlinearity, fuzziness, strong coupling and multi-objective of the pick-up mechanism of planetary gear train with ellipse gears and incomplete non-circular gear in optimization process, firstly, the kinematical model and optimization objective function were established. Using parameter-guided optimization method, the kinematical optimization software was developed with Visual Basic visualization platform. A set of parameters were obtained and optimized which could meet the work trajectory requirements of pick-up mechanism. Finally, the fetching test was carried on experimental prototype to verify the rationality and effectiveness of the parameters of pick-up mechanism.
