Methodology of Modular Design of Construction Machines
Abstract. The following paper describes a method of structural design of modular mobile working machines, specially wheeled telescopic excavators. Today in the automotive industry, engineers prefer modular design, platform vehicles, to increase the efficiency of the process of designing newly released models. In the design of construction machinery, it is also possible to choose a common platform for a group of devices. For the research of modular design methodology, it was drawn up several excavator options. Students of engineering study have modelled within two years, the conceptual study of wheeled telescopic excavator of weight category up to 14 tons. Some design solutions and used components cannot be presented in this work, because of patent protection. The design of the selected components is also in ownership of manufacturing company, the potential machine manufacturer. This model of wheeled telescopic excavator presents proposal of new size range of universal finishing machine, which will appropriately complement the company manufacturing program. For this machine, there were selected variants of different chassis, various powertrain systems and work equipment’s. The chassis options include wheeled chassis, tracked chassis and self-propelled chassis with its own power unit, which generally replaces drivetrain in excavator upper body. Work equipment, telescopic boom as a set of modules provides many more design variants. Base variant, wheeled telescopic excavator.
