AB  - In this paper, structural reliability is applied to compare the original
bucket wheel boom (BWB) of excavator SchRs 740 and the series of boom
structures obtained by lengthening the original boom from 0 to 10 m.
Stress field of BWE is acquired using finite element method. Then, stresses
and yield criterion are modeled using probability density functions to
account for uncertainties in their randomness. This stochastic approach is
used to determine BWB’s reliability, reliability index and probability of
failure, with respect to various cases of optimization, namely, structure
lengthening. Consequently, it enabled the evaluation, quantification and
comparison of overall response of the similar structures taking into
account range of stress rather than conventionally based single value
approach. So, structural reliability approach can be used to evaluate,
compare similar structures and thus, provide more sophisticated
assessment than most of the structural analysis that are deterministic in
their nature.

AB  - 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 for the selection of excavator optimal parameters are created, and therefore for determining the required length of the boom. In this paper, analysis of dynamic and static behaviour of boom extended from 1 to 10m with a step 1m was done. The maximum possible extension is defined as the aspect of the structural performance, dynamic behaviour and stress field. Finite Element Method (FEM) is used to obtain natural frequencies, displacements and stresses.
