Abstract: For multi-actuator system driven by single pump in
construction machine, a new method based on pressure difference sensing
and meter-in flow rate feedback control is given to fully use the
hydraulic energy from pump on the condition of fulfilling the harmony of
the system. According to theoretical analysis, a control strategy
combining priority control with flow division control is proposed and
tested. Theoretical analysis and experimental study show that the
unreasonable distribution of flow rate could be avoided, and the system
becames more harmonious and efficient.
Key words: Construction machine Multi-actuators Flow division
control Pressure decrease sensing
