Torsion Response and Vibration Suppression of V~ind-excited Buildings
A series of wind tunnel model tests and theoretical analyses were conducted to investigate torsion excitation, response and vibration suppression of wind-excited buildings. An aeroelastic model for pure torsion vibration was developed and the aeroelastic test results were compared with those obtained by other Wind tunnel test techniques. The comparison and practice indicated that this type of m...
متن کاملvibration control of multistory buildings by using tupe inversion diviceis
the application of energy absorbing systems in the structures are one of the main methods in attenuation of earthquake effects. in this paper, the vibration control of structures by using of tube inversion systems is considered. in this novel system, the energy is dissipated by the inversion of a metal tube. this energy dissipater has large energy absorbing capacity along with constant stiffnes...

Measurement of hand-vibration transmissibility by non-contact measurement techniques
Background: Workers who use hand-held vibrating tools may experience finger blanching attacks due to episodic vasospasm in the digital vessels. In occupational medicine, the pathological consequences to the exposure to handtransmitted vibration are known as vibration induced white finger (VWF). In many cases, workers are recommended to use anti-vibration gloves and a standard procedure (ISO 108...
متن کاملFundamentals of Vibration Measurement and Analysis Explained
However, the basic processes of measurement and analysis have remained essentially unchanged, just like the machines from which the vibration is measured. The results of the measurement and data analysis need to be compared with known standards or guidelines and decisions made as to whether the machine is acceptable for service or maintenance should be planned. Increasingly these processes are ...
