Abstract

The scientific paper deals with the multi-criterion optimization of the teeth that are used on the buckets of bucket wheel excavators. From past theory and practice, it is known that geometry of the tooth greatly influences the cutting parameters and the endurance and the strength of the tooth itself. The dependencies between the cutting forces, the penetrating forces, the specific energy on the rake angle and the relation between this last one and the robustness of the tooth are somewhat contradictory, so in the design of both the shape and the dimensions of the tooth, a multi-criterion optimization is necessary, in order to obtain the most lightweight tooth but with maximal rigidity and the best energy and force characteristics for a given excavated type of rock. The method presented in the paper uses Mathcad software to fulfill this task, and as a result three versions of teeth were devised for excavating overburden rock and/or lignite, suitable for bucket wheel excavators used in Romanian lignite open pit mines.
