Abstract
The rationality of powertrain parameter design has a significant influence on the traction performance and economic performance of electric tractor. At present, researches on powertrain parameter design mainly focus on electric vehicles, and electric agricultural machinery draw much less attention. Therefore, a method of powertrain parameter matching and optimization design for electric tractor was proposed in this paper, which was based on dual-motor coupling drive mode. The particle swarm optimization (PSO) algorithm based on mixed penalty function was used for parameter optimization. Parameter optimization design was programmed using MATLAB. A simulation dynamic model with optimization design variables of electric tractor powertrain was established based on MATLAB/Simulink. Compared with the simulation results before optimization, the objective functions were optimized and the traction performance of electric tractor was improved, which indicated the effectiveness of the proposed method.

Summary
With the deterioration of environments and increase of energy depletion, developing agriculture with environmental friendliness, resource conservation and high efficiency is prospective and necessary. When electric tractor is driven by single motor, it prefers selecting a motor with larger power, due to the heavy load requirement This will result in low efficiency under low load working conditions. For the same power requirement, dual-motor coupling drive mode can relatively reduce the capacity of each motor, which is conducive to increase motor load rate and efficiency, and improve traction and economic performance of electric tractor under different working conditions. This research described a method of powertrain parameter matching and optimization design for 25 horsepower small electric tractor based on dual-motor drive mode.
