Metody badania form odkształceń stojana maszyn elektrycznych.
PublicationOmówiono podstawy, cechy i zalecenia wykonania klasycznej analizy modalnej,eksploatacyjnej analizy modalnej i najnowszej analizy eksploatacyjnych form odkształceń (ODS FRF) w zastosowaniu do maszyn elektrycznych. Do analizy eksploatacyjnych form odkształceń sformułowano wzór działania na widmach oraz wprowadzono dekompozycję kształtu formy odkształceń. Na podstawie przykładowych badań silnika indukcyjnego małej mocy wykazano różnice...

The clamping selection method to reduce the vibration of large-size workpieces during the face milling process
PublicationThe article introduces a method for selecting the best clamping conditions to obtain vibration reduction during milling of large-size workpiece. It is based on experimental modal analysis performed for a set of assumed, fixing conditions of a considered workpiece to identify Frequency Response Functions (FRFs) for each tightening torque of the mounting screws. Simulated plots of periodically changing nominal cutting forces are...

The vibration-based assessment of the influence of elevated temperature on the condition of concrete beams with pultruded GFRP reinforcement
PublicationConcrete beams reinforced with glass fiber reinforced polymer (GFRP) bars subjected to elevated temperature have been experimentally studied. The influence of high temperatures on GFRP-reinforced concrete beams condition has been check both, destructively and nondestructively. The nondestructive tests foresaw vibration-based tests to obtain the natural frequency values after exposure to varying temperatures. The vibration-based...
