On June 3, Dal-Shik Jang, a researcher at Doosan Infracore’s Institute of Technology, presented a paper on the development of intelligent electronic hydraulic excavators and improved fuel economy at The 11th Scandinavian International Conference on Fluid Power (SICFP’09), held at Sweden’s Linköpin University, a highly respected university in the field of hydraulics.
The title of the presented paper was “Development of the Intelligent Robotic Excavator for the Autonomous Excavating System.” Mr. Jang presented the algorithm that realized a 14% increase in fuel economy through the automated hydraulic system and showed a demonstration video of the remote-controlled system that was developed.
The paper was co-authored by Senior Researcher Yong-Rak Cho, Senior Researcher Gi-Yong Kim, Staff Researcher Hyun-Shik Ahn and Director Jun-Hyun Jang of the Institute’s Hydraulic Technology Team.
Eminent professionals in the field of excavators attended the conference, which was based on “energy reduction,” including Prof. S. Helduser of Germany’s Dresden University, Prof. Monica Ivantysynova of the US’s Purdue University, and B.G. Persson, chief technology officer for the Swedish company, Parker. Attendees were particularly intrigued by the separation of the boom and the arm and the increased fuel economy through controlling the swing relief pressure. They also admired the fact that the development of cutting-edge, autonomous unmanned technology is being supported at a governmental level.
By introducing the company's advanced excavator technology at this conference, Doosan Infracore promoted its products and improved its brand image.
The Ministry of Land, Transport and Maritime Affairs has provided funding in the amount of 12 billion KRW for the “Development of Intelligent Excavator Systems” project, which began as a result of rising demand for unmanned excavator operations. The project has just seen the end of its third year.
The project is being carried out by 15 domestic industry-university-institute collaborative organizations and Germany’s Dresden University, which is very highly regarded in the field of electronic hydraulics. The project is led in Korea by Director Jun-Hyun Jang of Doosan Infracore’s Institute of Technology, while Researcher Dal-Shik Jang is in charge of the three sections of the research. In particular, Researcher Jang is carrying out the research through close collaboration with Prof. Helduser of Dresden University, as they are both alumni of Aachen University’s Institute for Fluid Power Drives and Controls (IFAS).
