The use of numerical methods in cutterhead dredger excavation unit optimization



Authors present a numerical and experimental approach to determine the reasons for not achieving required efficiency of cutterhead dredger. The scan of the cutting disc of the dredger was performed using a 3D scanner. In author’s method, in order to determine the efficiency of the dredger with respect of the cutting tool, numerical methods were implemented: Discrete Element Methods and Rigid Body Dynamics. Authors proposed to determine the efficiency of the dredger as a measure of the change in the load of the cutting disc, thus changing the moment on the wheel and the boom. Numerical simulations were performed for the model currently mounted on machine and for models with altered teeth position. A number of analyzes allowed authors to propose the correct placement of the teeth on the cutting disc. New arrangement of the teeth increased the efficiency of the dredger.

Host city and venue

Vienna (Wien) is the federal capital and largest city of Austria, and one of the nine states of Austria. Vienna is Austria's primate city, with a population of about 1.9 million (2.6 million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union.  Read more...
