ANSYS THE VARIANCES IN DYNAMIC CHARACTERISTICS OF THE DYNAMIC VIBRATION ABSORBER CAUSED BY PARAMETERS CHANGE

Quantitative analysis effects of random variation parameter on dynamic properties of dynamic vibration absorber with Monte Carlo method. The results indicated that in all of the parameters the variation of mass is most influential. The increase of the variability of the main system and dynamic vibration absorber mass coefficient can make the peak of magnification advance. It means resonance produces at lower frequency. It widens the band width of excited frequency which induces resonance. With increasing of variation of stiffness,the band width of frequency which produces multiple amplification factor extended too. However, the infection of damp variational parameter can not compared with mass and stiffness. When add the variety of the parameter of mass stiffness and damp, the peaks of P and Q die away. The new peak appears between them. It means the dynamic properties vibration absorber is removed from optimum.
