The initiative of Digital Transformation (DX) for the purpose productivity improvement and reforming work style has been more active in construction industry. In particular, research development autonomous machinery carried out with aim improving through construction. On other hand, Internal Model Control (IMC) system based on Database-Driven Modeling an excavator is developed by authors. Howev...

A group lubrication system of mechanical components for a walking excavator is proposed, the original design lubricator with pneumatic drive and controlled electro-magnetic valve developed

The purpose of thesis was to comprehensively develop the construction project a long reach compact excavator. Optimal solution selected and its frames were determined by carrying out classic structural calculations. Then, based on them, preliminary three-dimensional model designed in CAD environment. prototype subjected series verification calculations simulation tests using finite element meth...

In this paper a multi-agent based simulation and optimization framework was put forward to solve the aleatory and epistemic uncertainty in engineering design. Agent structures were designed to extract engineering knowledge from experiments and simulation and to communicate an internal message and domain engineering knowledge base. The framework can deal with complicated time-varying structure a...

Abstract The energy-saving of hydraulic excavators is evaluated by two significant indicators: operating efficiency (digging weight per unit time) and fuel consumption (volume consumed time). These indicators are only the final test results cannot quantitatively evaluate whole operation process excavator. In this paper, a complete set experimental protocols designed to quantify excavator collec...
