摘要:... The human comfort evaluation methods used in the analysis indicated that the composite floor presented excessive vibrations. Hence, it was detected that this type of structure can reach high vibration levels that can compromise the user’s comfort. In addition, the use of m...

摘要:A new approach of marine vibration problems is given, showing that for modern, high powered ships excessive hull vibrations at service r.p.m. cannot be explained by hull resonances. The fundamental cause is the increased power. Therefore the solution of present-day vibration prob...

摘要:... However, most ROP optimization models do not consider the effect of drilling vibrations, a major ROP inhibitor. To resolve this limitation, this paper introduces a workflow that combines the ROP optimization process with a machine learning-based vibration model. This model de...

摘要:... In many cases the dynamic behaviour of steps is almost independent from the rest of the staircase, causing a phenomenon designated as local vibrations, which could be much more severe than the global vibrations of the staircase.(#br)In order to avoid this problem, this paper ...

摘要:... Hard disk drives (HDDs) in particular, are critical components in laptop computers whose read/write performance is severely affected by excessive vibrations. Here we take a system-level approach to design an optimal vibration isolator so as to minimize the transmitted vi...

摘要:Annoying vibrations in grandstand structures have been receiving more attention due to the increasing slenderness of the architectural components and the complexity of the crowd loading for engineers. The vibration serviceability checks under these conditions become a challenge i...

摘要:Structural control devices facilitate the construction of lightweight structures by suppressing excessive vibrations that arise from the reduced self-weight. Most of the current structural control systems are permanent installations designed to control particular structural prope...
