Ships’ hull usually works in a hard environment caused by static forces and permanent dynamic loads. Modeling of dynamical reactions could bring information to the designer for recognizing the level of hazard for hull structure and propulsion system. A paper presents a proposal of identification of a degree of hazard the ships hull forced from underwater explosion. A theoretical analysis was made...

The authors of this article have been looking for new parameters and dynamic characteristics which can be applied to the non-destructive testing of welded joints. All the characteristics have been based on the recorded data generated during the vibration tests of welded joints both with and without failures. This article has dealt with the methods of assessing welded joints using either 2D or 3D time-frequency...
The paper presents the results of laboratory simulation tests of a suspension system for a car seat. The first part of the paper contains a description of the experiment, paying particular attention to the conditions in which the tests were conducted and the properties of the electrically controlled damper, which was mounted in the tested car seat’s suspension. Graphs of the damper’s operation were...
