Selected problems relating to the dynamics of block-type foundations for machines

Atypical but real practical problems relating to the dynamics of block-type foundations for machines are considered using the deterministic approach and assuming that the determined parameters are random variables. A foundation model in the form of an undeformable solid on which another undeformable solid modelling a machine is mounted via viscoelastic constraints was adopted. The dynamic load was defined by a harmonically varying signal and by a series of short duration signals. The vibration of the system was investigated for the case when stratified ground (groundwater) occurred within the side backfill was present. Calculation results illustrating the theoretical analyses are presented.

期刊介绍： Mining Scince. Scientific Papers of the Department Geoengineering, Mining and Geology of the Wroclaw University of Technology. The journal publishes original papers on mining and geology, geo-engineering and the related issues. The journal is devoted to the following topics: fundamental research in mining, underground and open-cast mining technologies, blasting technology, design and construction of mines, geomechanics and geotechnical engineering, mine ventilation, fluid mechanics and its application in mining, mining machinery and condition monitoring, mineral processing, environmental protection and waste utilization. The journal also accepts papers concerns geoengineering which is a sciences covering mining construction, geotechnical engineering, GIS, and earth sciences.
