Abstract:

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.

Key words: agricultural engineering, agricultural machinery design, cultivating machine, mechanical weeding, multi-objective optimization design
