Dual-channel Potential Energy Recovery and Load Balancing Methods for Large Hydraulic Excavators
Published 2024-11-01“…The specific manifestation of these problems is that the boom stalls or almost stops descending. To solve these problems, the research object here is a large hydraulic excavator, for which is proposed a direct/indirect dual-channel boom potential energy recovery system comprising a three-chamber balance cylinder, two accumulators, and a fan motor.Methods In this study, the traditional single accumulator recovery channel (single-channel system) is changed to a dual accumulator recovery channel (dual-channel system), where the three-chamber balance cylinder and accumulator 1 form a direct recovery channel, while the fan motor and accumulator 2 form an indirect recovery channel. …”
