Control Strategy and Experiment on Loader Digging and Loading with Intelligent-resistance Reduction

In order to reduce the power loss caused by tire slippage during the shoveling operation of the loader,this paper proposes an intelligent drag reduction shoveling control strategy based on the destruction of material compactness.Based on theoretical analysis,the formation mechanism of operating resistance during shoveling of the loader is clarified,and a new idea of achieving drag reduction insertion by automatically lifting the boom to destroy the compaction core is established.An optimization scheme based on the existing hydraulic system was proposed,and an intelligent drag reduction shoveling control strategy for loaders based on the wheel speed difference was designed.Subsequent shovel loading experiments proved that this control strategy can automatically raise the boom to destroy the compactness of materials when slipping occurs during the shovel loading process,reduce operating resistance and reduce tire slip time,and avoid power loss.
