The swing system can be optimized to further improve the energy efficiency of mining excavators. The current swing systems of mining excavators operate as follows: When mining
Among these, the hydraulic energy storage component (HESC) is crucial to the entire HER system, as it directly influences energy utilization efficiency [27, 28, 29]. Therefore, effectively utilizing HESCs is essential for optimizing HER system performance [30, 31]. A hydraulic accumulator is the primary HESC used in the HER system.
This paper proposes a novel hydraulic energy storage component (NHESC) that integrates hybrid energy storage through the use of compressed air and electric energy. The system configuration of the NHESC is first designed, followed by the modeling of key components and analysis of working states.
Experimental results show a 17.6% energy savings, despite the boom falling time being 1.87 times longer than in a conventional system. Zhang et al. proposed an electro-hydraulic energy storage damper for off-road vehicles, offering an effective solution for energy harvesting and improving fuel efficiency.
