Abstract

To cope with the low energy efficiency issue caused by load difference between multiple actuators in the load sensing (LS) system, a hybrid distributed-centralized load sensing (HDC-LS) system is proposed in this study for electrified construction machinery. The idea is to establish a hybrid distributed-centralized actuator (HDCA) by connecting a distributed actuator and the original hydraulic cylinder (called centralized actuator) parallelly to balance load difference. Two types of actuators are considered for the distributed actuator: electro-hydrostatic actuator (EHA) and electro-mechanical actuator (EMA). A torque controller of the motor is proposed for the distributed actuator to reduce the energy loss of the pressure compensator and recover the potential energy. Moreover, a design criterion is established to determine the main parameters of the distributed actuator and redesign the control valve of the centralized actuator. A simulation model with a 6 T excavator is established to validate the proposed system. Compared with the traditional LS system, the results show that the energy consumption of the battery is reduced by 11.4 % using EHA as the distributed actuator and reduced by 13.6 % using EMA. Meanwhile, the motion performance of the proposed system is consistent with that of the traditional LS system. The proposed system is beneficial for reducing the energy consumption and battery capacity of electrified construction machinery.
