Anglický název: Random excitation of tubes with gaps

Abstrakt CZ: The fluid flowing crossover the tubes of heat exchangers is resource of aerodynamic excitation. The tubes are supported by support plates. Tubes go through this support plates with gapes. The existence of this gaps costs nonlinear behaviour of the whole system. Random excitation is supposed and dependence of vibration stability on the gap and on the flow velocity is studied.
