Abstract

In this paper sizing the powertrain of battery electric tractor (BET) including major farming implements are investigated for various real world driving patterns. Powertrain components are modelled using torque-load characteristics which are function of speed, acceleration, plowing implement and depth of plowing and texture of the soil. Effect of load variations on powertrain performance and energy consumption are also explained in detail. In this powertrain design major farming implements like chisel plough, mould board plough, field cultivator, sweep plough are considered. Tractor hauling a trailer carrying goods with 2000 kg weight is also considered for powertrain design. Typical operating velocities of 18, 15 and 25 kmph are taken for sand, tillage and asphalt surfaces respectively for tractor trailer applications and 7 kmph for plowing applications. The dynamic model of the powertrain is modelled in MATLAB/SIMULINK. PMSM is selected as a traction motor and its performance is evaluated in MATLAB/SIMULINK. Same has been verified using real-time Hardware in loop (HIL) simulator with help of OPAL-RT (OP5700).

电池电动拖拉机动力总成部件尺寸与能耗、驱动模式和使用牵引电机的性能评估

本文研究了包括主要农具在内的纯电动拖拉机在各种实际工况下的动力系统选型问题。动力总成部件采用扭矩负载特性进行建模，该特性是速度、加速度、犁具、犁深和土壤质地的函数。并详细阐述了负载变化对动力系统性能和能耗的影响。在动力系统设计中，主要考虑了凿子犁、板犁、田耕机、扫犁等农具。牵引着2000公斤重货物的拖车的牵引车也被考虑在动力系统设计中。典型的操作速度分别为18、15和25公里每小时的沙子，耕作和沥青表面的拖拉机拖车应用和7公里每小时的耕作应用。在MATLAB/SIMULINK中建立了动力总成的动力学模型。选择永磁同步电机作为牵引电机，并在MATLAB/SIMULINK中对其性能进行了评估。在OPAL-RT (OP5700)的帮助下，使用实时硬件在环(HIL)模拟器对其进行了验证。
