Abstract: Abstract: A boom potential energy recovery program for hybrid excavator was proposed which based on hydraulic accumulator and battery, and Multi-objective optimization methods was used to match the parameters of key components of the energy recovery system. Not only that, for the recovery system, the paper established simulation model and control strategies and analyzed the effect of parameter matching and control methods by simulation. At last the recovery effect and handling performance was studied by build hybrid excavator test platform of boom potential recovery system, and found that not only the recovery program is feasible but also the system operation performance is stable and parameters matching effect and energy recovery rate is good.
