Dynamic analysis of viaducts’ behavior on dynamic action
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
The dynamic modeling, aims to analyze the dynamic behaviour of the viaduct to external actions from the road traffic and / or seismic movements. The rigid model with six degrees of freedom with viscoelastic links triortogonale with elastomeric bearings is based on the dynamic analysis adopted in this research.

On the Stability of a Class of Non-Ideal Systems
A vibrating system is said ideal when its excitation is not influenced by the response of the system. When the excitation is influenced by the response of the system, the system is said non-ideal. A new degree of freedom...
Noise Mapping in Hungary and Romania
The First round of the noise mapping obligation according to the European Noise Directive (END) has been finished recently. By the end of 2007 all member states should have prepared their noise maps according to the dire...
Study of noise directivity at household air conditioning installations
This paper presents the experimental determination in various operating modes of noise directivity at household air conditioning installations. To conduct the experimental study a measurement stand was built inside the a...
The influence of the damping coefficients to the hunting motion stability of the bogies
Conventional railway vehicle systems exhibit lateral instability phenomenon doe to selfinduced oscillations of the rigid axle wheelsets, which increases component wear and imposes operating speed limits. To improve the s...
Dynamic Response Analysis of the Road System Compaction According to the Forced Vibration Mode
Mechanical systems are composed of elements of movement, elastic rigid bodies and joints. If referring to moving elements they are materialized by bodies of different geometrical configuration and are connected to each o...
