New research published

As always we are very happy to announce that members of DMC have published another research paper. This time it is related to dynamic modeling of vibrating sieving screen used in the mining industry. The paper has been published in the special issue of Shock and Vibration journal entitled “Advances in Fault Diagnosis and Defect Detection in Mechanical and Civil Engineering”. The work presented in this paper has been funded by OPMO project. Full citation can be found on the research page.

Two new articles published in MSSP

We are happy to announce that members of DMC recently published two articles in Mechanical Systems and Signal Processing journal. Both of them present newly developed vibration signal processing techniques mainly aimed for machine diagnostics purposes (see references below). The work presented in those papers has been funded by MAMMA and OPMO projects. Full citations can be found on the research page.

DMC at XLVII Ogólnopolskie Sympozjum DIAGNOSTYKA MASZYN

Yet another conference visited regularly by the members of DMC team is the Machine Diagnostics Symposium (XLVII Ogólnopolskie Sympozjum DIAGNOSTYKA MASZYN) organized annually by Silesian University of Science and Technology in Wisła, Poland. The most commonly discussed topics were: machine diagnostics using vibroacoustic techniques, simulation-aided diagnostics, IT technologies in diagnostics and diagnostics of the means of transportation.
