摘　　要：为获得理想的苗间机械锄草效果,在建立了机械锄草齿运动轨迹数学模型的基础上,结合农艺对机械锄草参数的限定及要求,建立了多目标优化模型,并利用Matlab7.0优化工具箱得到最优解。以作业速度、锄草齿数目、锄草齿在圆盘上均布半径和圆盘转速4个主要参数的最优组合为设计基础,通过Pro/E软件进行实体建模与仿真,验证了多目标优化设计的正确性,为大型中耕除草机的设计提供了理论依据。Based on mathematical model of mechanical weeding tine trajectory and parameters limitation and request at agronomy, a multi-objective optimization model was proposed for obtain ideal mechanical weeding effect. And by using Matlab7. 0 Optimization Toolbox we obtain the optimal solution. The optimal combination of four main parameters includes the operation velocity of the unit, tine numbers, distributing over radius of the tines and revolution of disk was as the foundation of design. Through Pro/E solid modeling and simulating,the result of simulation verifies that the multi- objective optimization design is correctness, and provides a theoretical foundation for designing large sized weeding-cultivating machinery.
