The paper presents the collocation method of determination damping coefficients of structural vibration. Moreover, usage of this method for several different building structures have been presented.
Mechanical vibration dampers (MVD) can be used for reduction of tower type structures vibrations. A method of determination of optimum parameters of MVD mating with this type of structures was described in [1]. The worked out computational method became the basis for design solutions. Talcing in the consideration the type of the structure (tower), the analysis concerned the amplitude-frequency characteristic...
General description of fluids applied to viscotic torsional dampers are presented in this paper. Results of experimental investigations of fluid viscosity influence on dissipated energy and angle of torsion of crankshaft as well as results of numerical computations are also included.
Cables used in overhead transmission lines and cable-stayed bridges are subjected to large vibrations causing fatigue damages of the cable and assemblies. Wave motion and vibration occur mainly due to vortex shedding, rivulet formation, galloping and buffeting. In the paper the problem of optimal choice of the distributed damping force suppressing the waves traveling along the cable is considered...
In the paper a new method of parameters identification of the three parameters fractional, rheological Kelvin model is presented. The parameters are estimated using results obtained from dynamical tests. The proposed method is simple and effective. Results of example calculation are presented and briefly discussed.
Problem of active reduction of vibrations of continuous system by means of punctual action is formulated in this paper. Model of beam with taking into consideration internal damping material of beam is considered. Forms of individual vibrations are determined by Fourier's method. Analysis of proposed way of reduction of vibrations is carried out by Galerkin's method. There are results of numerical...
