抄録

<p>The occurrence of the low frequency vibration in vibroimpact systems such as vibrating sieve reduces the reliability f the system and precludes normal operation when its amplitude is excessive. In order to establish guidelines to suppress e low frequency vibration, this paper derives analytical expressions for optimal parameter values of a dynamic absorber or a free vibration model and compares them with numerically obtained optimal parameter values of a dynamic absorber or the vibroimpact system. The results demonstrate that the two sets of optimal values are close to each other, which uggests the effectiveness of the design of a dynamic absorber to suppress the low frequency vibration through the optimal esign for the free vibration model.</p>
