Numerical assessment of stability of the ball vibration absorber
Fischer, Cyril ; Náprstek, Jiří
The ball vibration absorber (BVA) is in principle a heavy ball rolling inside a semi-spherical cavity. It is a convenient alternative to the usual pendulum-based dampers. The dynamics of the real ball absorber is significantly more complicated in comparison to the pendulum one. However, the numerical examination of the non-linear model of the BVA indicates that its resonance behaviour is similar to the spherical pendulum. Despite the theoretical differences, the resonance curves in both cases form similar patterns. It seems that detailed study of both separate cases can provide complementary results, whose parallels appear in the other model.
Complex nonlinear model of cable stayed bridges
Malík, Josef
The goal of this paper is to propose a complex non-linear model of cable stayed bridges describing vertical and torsional oscillations of a road bed, vibrations of pylons, non-linear behaviour of cables, and influence of gravitational and aerodynamical forces.
