针对椭圆-不完全非圆齿轮行星系蔬菜钵苗取苗机构的参数优化是具有非线性、模糊性、强耦合性的多目标复杂优化问题，建立了该机构的运动学模型及优化目标函数，运用参数导引优化方法，通过Visual Basic可视化平台开发了取苗机构运动学优化软件。应用该优化软件可方便地获得的一组机构参数，通过虚拟仿真可以看出所优化的参数能够满足取苗工作轨迹要求。试验样机进行了取苗试验，验证了取苗机构参数的合理性和有效性。

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.
