JUDGEMENT OF POSSIBILITIES OF DECREASE OF VIBRATION MAGNITUDE OF FORCED RESPONSE BY ACTUATING KINEMATIC EXCITATION EFFECT


Abstract eng:
The task is to determine time history of a kinematic excitation so that after the initial transient component dies out, the magnitude of displacement a kinematicaly excited system has been lower than the magnitude of the system without kinematic excitation. The best solution of the investigated problem can be calculated by means of a procedure using minimization of the functional. However, numerical simulations shows that due to complexity of analysis proposed approach is not useful for solving systems with more than one of degree of freedom. They also tell that the best approaches to decrease a vibration magnitude of a rotor system supported by hydrodynamic bearings are methods using linearization equation of motion.
