Opis:: A technique for stabilization of resonant frequency is proposed in this paper. An additional power circuit, a compensator that allows keeping constant resonance frequency was introduced by the authors. In the presented solution the resonant circuit frequency stabilization is achieved by forcing a zero phase shift between the current and the voltage of the main switching module.

Opis:: Dockside cranes must retain adequate strength requirements that will not endanger the safety of their use. This may cause the fact that the impact of vibration on the structure exposed to horizontal forces caused by the transport of goods loading and transverse forces caused by wind can be dangerous for the correct operation of the machine. In addition, there are often consequences of climate-related environment, with fatigue - dynamizującymi destruction of the object. Dynamic loads may cause effects so devastating or catastrophic lead to their destruction [1,6,9,13,21]. Recognizing the need to improve methods for testing of lifting equipment for the purpose of assessing their condition and assess the safety factors in this paper attempts to study the destruction of the structural element of the lift with the help of theoretical methods of modal analysis [4,8,12,21].

Tytuł:: Investigations of harbour brick structures by using operational modal analysis

Opis:: Historic harbour brick objects are subject to large dynamic loads clearly reflected by generated vibration processes. The vibrations may affect state of serviceability of structures by lowering comfort of persons working there as well as possible reaching the level hazardous to safety of the structures. The effect of vibrations to structure is mainly manifested by additional stresses in a given cross-section, which are summed up with those resulting from static loads. Moreover often occur consequences associated with environmental conditions and fatigue of materials which accelerate destruction of the objects. Therefore the dynamic loads may cause damaging effects in buildings of various structural types or even lead to their catastrofic destruction. Judging the necessity of improving the quality assessment methods of building structures for purposes of estimation of their state as well as safety factors for brick structures (see PN-B- 03002 standard, p.3.1.3 and 4.6), the author of this work undertook an attempt to investigate destruction process of selected building structures by using the method of operational modal analysis.
