Analysis of Torsional Oscillations Using an Elastic Auxiliary Element

20 ANALYSIS OF TORSIONAL OSCILLATIONS USING AN ELASTIC AUXILIARY ELEMENT [Pg.832]

Equation (17.295) together with Eq. (17.291) determine the real zeros. For small values of the argument XI, we can write [Pg.833]

If the viscoelastic material under consideration is a standard solid governed by a single relaxation time, then by combining Eqs. (17.281) and (17.299), we obtain [Pg.834]

On the other hand, the comments made for the case of nonutilization of an auxiliary elastic element in relation to the different types of response are also pertinent in the present context. In fact, if the trigonometric functions appearing in Eq. (17.293) are approximated by [Pg.834]

The appearance of a double pole is not a serious problem, because we can make the approximations [Pg.835]
