双电机拖拉机动力系统参数匹配及优化设计
Parameter Matching and Optimization Design of Power System of Dual Motor Tractor
摘要
Abstract
The rationality of the parameter design of the power transmission system has an important influence on the field traction performance of the electric tractor.At present,the research on the parameter design of the powertrain mainly fo-cuses on the electric vehicle,while the research on the electric agricultural machinery is less.Aiming at the above prob-lems,a parameter matching and optimization design method of electric tractor power system based on dual-motor coupling drive mode is proposed.Particle swarm optimization based on hybrid penalty function is used to optimize parameters,and MatLab is used to write parameter optimization design program.Based on MatLab/Simulink,a dynamic simulation model of electric tractor powertrain with optimized design variables is established.The research results show that,compared with the simulation results before optimization,the objective function is optimized,which improves the traction performance of electric tractors.The effectiveness of the proposed method is shown.关键词
