International Conference VIBROENGINEERING 2014 was held on October 13-15, 2014 in Katowice, one of the main industrial conglomerates in Poland. Authors from different Countries (Japan, China, Colombia, Russia, Kazakhstan, Latvia, Belarus, Lithuania, Czech Republic and Poland) presented their latest research during the conference. A platform for authors was provided for exchanging ideas and research together. The venue for the conference was in Novotel Katowice Hotel, City Hall and Silesian University of Technology.

The problems of vibration and vibration damping in modern means of transport and medicine.
W prezentacji przedstawione zostaną zagadnienia dotyczące drgań w obszarze środków transportu i medycyny. Omówione zostaną zagadnienia drgań i ich tłumienia z wykorzystaniem tłumików semiaktywnych w nowoczesnych środkach transportu powstających w projekcie Eco-Moilność. W zakresie medycyny pokazane zostaną techniki amortyzacji drgań oraz wykorzystania drgań w leczeniu złamań z wykorzystaniem mechatronicznych stabilizatorów ortopedycznych
The presentation will be covering issues concerning vibrations in the area of transport and medicine. Author will discuss selected problems of vibration and vibration damping using semi-active dampers in modern means of transport resulting in the project Eco-Mobility. In the field of medicine the talk will be showing techniques of vibration damping and the application of vibrations in the mechatronic orthopedic stabilizers to treat bone fractures.
Prof. Ass. Andrzej Grządziela, Ph. D., D. Sc., , born in 1965, is a retired Captain of the Polish Navy and has a position of the Associate Professor in the Mechanical - Electrical Faculty of the Polish Naval Academy (PNA). His interesting area is technical diagnostics, vibroacoustics and naval engineering. Presently he has a position of the V-ce President of the Polish Society for Technical Diagnostics.

The paper presents the parameters of the pressure wave incident on minehunter hull structure modeled on the simplified vessel hull of Kormoran II project. Study describes the phenomenon of underwater explosion. The model used in the study is the latest model of the shock wave in this type calculations. Problems that results from the application of the acoustic medium and its response for the given load.
M. S. Cao is a professor at the Engineering Mechanics Department and director at the Central Experimental Laboratory of Mechanics and Materials in Hohai University, China; Scientist in Chief at the Center of Jiangsu Province 2011 Cooperative Innovation Research on Structural Safety and Health; Chair professor of "Qing Lan" innovation program for science and technology; Marie Curie Fellow – Experienced Researcher at the Polish Academy of Sciences. He received his PhD degree in hydraulic structural engineering from Hohai University in 2005 and obtained a Top-100 Excellent Doctoral Dissertation Award in 2008. He has six years’ experience of conducting research in The Hong Kong Polytechnic University, Washington State University in the United States, and the Polish Academy of Sciences in Poland. He is the author of more than 70 journal papers. Current research interests include structural acoustics and vibration, structural health monitoring, applied soft computing, wavelet analysis, and multiscale dynamic modeling and simulation.
In structural health monitoring, modal curvatures are widely used in damage diagnosis in beams and plates, allowing not only indication of the occurrence of damage but also determination of its location, with no need for prior knowledge of the structure being inspected. Notably, however, modal curvatures have an intrinsic deficiency of susceptibility to noise involved in measurement, the noise effect easily masking genuine damage feature in the modal curvature. To overcome this deficiency, a new philosophy of adopting wavelet transform theory to create wavelet modal curvatures has been formulated by Prof. Cao and colleagues, from which a several interlinked new concepts have been derived, including 1D wavelet modal curvature, 2D wavelet modal curvature, and complex wavelet modal curvature. The multiscale property of wavelets endows these newly developed modal curvatures with the predominant characteristics of robustness against noise together with intensification of slight damage. A set of experimental cases is provided to demonstrate the capability of wavelet modal curvatures to identify complex damage in aluminum and composite structures.
