Vehicle Vibration Prediction — Why and Howganisers selected a speaker from the helicopter industry because of our reputation in controlling vibration, or because of the high vibration found on helicopters! However, it is fair to say that the vibration standard of helicopters is not as good as most other modern forms of transport, and theref

Towards an Integrated Procedure for the Mathematical Modelling of Ship Vibrations. Furthermore, based on certain engineering judgements, a practical modelling of the global vibrations can usefully be carried out within the design timescales. The basic method used is the Finite Element Method but substructuring techniques are appropriate as a means whereby the maximum problem siz

Acoustics in Marine Structuresh generates high noise levels. Two features which are perhaps more particular to ships are that the machinery is installed in a lightly damped steel structure and, in many cases, the people must remain in the noisy environment for periods of up to several weeks.

A Finite Element Solution for the Prediction of Transmission Loss and Radiation Efficiency of Panelspter panel systems..Numerical algorithms have been developed to compute radiation efficiency and transmission loss for any general 2-dimensional panel system modelled by conventional finite element analysis. The algorithms were validated by comparison with three independent references.A detailed err

Free Vibration Characteristics of Laminated Orthotropic Thin Cylindrical Shells with Free Edgescteristics of composite shells is undoubtedly of great importance in modern technology. It is, therefore, not surprising that the recent interest in filamentary composites has grown so high and the papers on the vibration characteristics of composite cylindrical shells have started appearing regular

Seismic Vibrational Loadings Induced by Rocking of Free-Standing Bodiesfects may be represented as inertial body forces in both horizontal and vertical directions applied to the bodies. Typically the movements have a short duration of several seconds and are most active in a limited frequency range, e.g. 0.5 to 25 Hz. Peak floor accelerations may be about 0.2g horizont
