Optimization of the bucket wheel boom length using structural reliability approach

Construction and Mining Equipment and Technologies

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

Host city and venue - Belgrade

Belgrade is the capital and largest city of Serbia and a city of very tumultuous history. Belgrade was the capital of Yugoslavia from 1918 to 1991. It is located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. It is one of the oldest cities in Europe and since ancient times it has been an important traffic focal point, an intersection of the roads of Eastern and Western Europe. Read more...
