Dynamic behavior and stress field of excavator SchRs740 extended boom
Апстракт
Bucket wheel boom represents the most loaded
and the most responsible part of the excavator
structure, participating only with 6 to 13% in the
entire excavator weight. Its length is selected
depending on the technological requirements of
mining deposit, and it has to be adjusted with the
designed possibilities of the excavator. At the
request of mining technology that is in compliance
with the soil-mechanical properties of deposit,
conditions are created for the selection of
excavator optimal parameters, and therefore to
determine the required length of the boom. In this
paper, analysis of dynamic and static behavior of
boom extended from 1 to 10m with a step 1m was
done. The maximum possible extension is defined
as the aspect of structural performance, dynamic
behavior and stress field. Finite Element Method
(FEM) is used to obtain natural frequencies,
displacements and stresses.
