Research Hydraulics

Hydraulic systems of large scale, as can be found in mining excavators, have typically been based on simplicity and durability. Typical architectures are open-centre hydraulic systems, which were designed with robustness and productivity in mind; however, they lack competiveness with other hydraulic systems in terms of energy efficiency. Displacement control has shown a promising potential especially in multi-actuator machines such as excavators. At the Technische Universität Dresden, an open-loop displacement control system was compared with today’s valve-controlled drive system in a mining excavator.

1 Introduction

In recent years, there has been various research performed in displacement control (DC) systems. A simplified circuit of a single rod DC actuator is shown in Figure 1, as it was proposed in [ 1]. The storage of the differential volume of the single piston rod in an accumulator, allowed DC linear actuation to enter the mobile machinery sector. The current state of the art...
