Experimental and numerical investigation of vibroimpact system with Hertz's contact
Půst, Ladislav ; Kocanda, Lubomír ; Peterka, František
The static characteristic force versisus deformation of teh used hemispheres made of weak elastic material was measured and used as a mathematical model of Hertz's stops. Measured dynamical properties agree with response curves obtained by numerical simulation in the resonance influenced by the strong nonlinearities very well.
Frequency modal analysis of liquid/gas interaction in cylindrical container covered by thin circular plate
Horáček, Jaromír ; Gorman, D. G. ; Griffond-Boitier, F.
The aim is to determine frequency-modal characteristics of the coupled system and to show when the fluid-structural and/or liquid-gas couplings are important for the dynamic behavior of the structure or fluid. A general theoretical solution is derived and the analytical-numerical results are partially compared with results obtained by finite element method (FEM) using ANSYS program code.
Motion of the dynamic impact damper
Peterka, František
Properties of the tuned dynamic impact damper is studied by numerical simulation. Different regimes of the system response on the harmonic excitation is evaluated and regions of existence and stability are ascertained. Specified behaviour as grazing, period doubling, saddle-note and Hopf bifursations are explained.
