Integrity assessment and determination of residual fatigue

Nov 01, 2019 · 2. Dynamic loads at the bucket-wheel excavator during service. Most components and elements of vital structures of bucket-wheel excavators are subjected to complex dynamic loads, which depend on conditions of exploitation (resistance to digging and own oscillations) in the stationary and non-stationary operational regimes of bucket-wheel excavator drive …

State analysis of the vital steel structure of the bucket

Taking into account the fact that the user of the bucket-wheel reclaimer does not own the design and technical documentation, damage repair was carried out under the assumption that the lattice structure of the operators' cabin was made of structural steels, which are mostly being used for the manufacture of bucket-wheel reclaimers.

Sustainability | Free Full-Text | Simulation of the Time

Aug 12, 2019 · A boom model was created for an ERc 1400-30/7 bucket wheel excavator, and was used to analyze the time response of the loads generated by the bucket wheel during excavation. We defined a mathematical model of the resultant of the excavation forces—which are the main source of vibration of the boom structure—and we determined the static

Vibration as deciding parameter during revitalization

After years of excavator`s operation in adverse conditions, one can expect a ratio between the bucket wheel drive and bucket wheel boom which may lead to impairment of structural integrity. Finite elements method is defined as a diagnostic tool for the anomalies occurrence prevention during operation, and the measured acceleration as a proof of the model's correctness i.e. …
