Lightweight Design of Sugarcane Harvester Turntable Under Multiple Working Conditions
Cane harvester turntable subjected during operation through bilateral pits oversteer condition and the load torque act-ing pits,stress complex,requiring multiple optimization condition considered.ESO multiple working conditions due to the impor-tance of optimization methods between different operating conditions not considered difficult to obtain global optimal solution.Therefore,a multi-objective topology optimization function is proposed.The linear weighting method with weights is used to coor-dinate multiple objective functions,and the mathematical model of multi-condition topology optimization is constructed.The ana-lytic hierarchy process is used to determine the weight coefficients of each operating condition.Perform multi-objective topology op-timization to obtain the optimal distribution of materials.The optimization results show that after optimization,the maximum stress and maximum displacement of the turntable structure are reduced,and the strength and rigidity requirements are met,and multi-objective simultaneous optimization is achieved.
