Evaluation for Energy Saving Effect and Simulation Research on Energy Saving of Hydraulic System in Hybrid Construction Machinery

Development of hybrid powered hydraulic construction machinery

“…Andersen et al For hydraulic excavators, Zhang et al [26] put forward a simulation study on the energy saving scheme with hydraulic motor regeneration for hydraulic actuators. The proportion of the regenerated energy for each actuator and the energy saving effects were calculated.…”

Systematic approach in the hybridization of a hydraulic skid loader

“…Several energy-saving options can be considered to recover, store and reuse this energy. Much research has been carried out in this direction, as detailed in [3][4][5], which has also confirmed the validity of the usage of hybrid power trains in the field of construction machinery. This paper reports on the design and development of different electric hybrid versions of an existing skid loader.…”

Multi-objective optimization for hydraulic hybrid vehicle based on adaptive simulated annealing genetic algorithm

“…After the introduction of hydraulic accumulator, the engine is decoupled from automobile load and operated in high efficiency region. Hydraulic accumulator has the advantage of higher power density and the ability to accept the high rates and high frequencies of charging and discharging, both of which are not favorable for batteries (Peng et al, 2006;Wang et al, 2005;Lin et al, 2003), therefore hydraulic hybrid technology is well suited for luxury passenger cars, sport utility vehicles, lightduty trucks and heavy-duty trucks.…”
