Abstract:
Wheel loaders are widely used in construction projects. In order to reduce
pollution and energy consumption, major wheel loader manufacturers are
developing electric powertrain technology. Our main research goal is to reduce
the energy consumption of a pure electric loader. This study is intended to
build a vehicle simulation model of a multiple drive motor electric loader.
According to the common working conditions and empirical formulas of the loader,
the simulation data of the electric loader are calculated. The torque
distribution control strategy based on the optimal efficiency of the motor is
designed for the multiple drive motor electric loader and is compared with the
equal proportion distribution control and the axle load ratio distribution
control through simulation analysis. The simulation results show that the
proposed torque distribution control strategy based on motor optimal efficiency
can reduce energy consumption by 7–12%.
