摘要
研究一类质量－弹簧系统的简谐受迫振动．弹簧为黏弹性材料，其特性由分数导数型本构关系描述．求出了系统的稳态响应，并讨论了材料黏性系数对幅频特性的影响．
Forced vibrations of a mass-spring sys- tem are investigated. The spring is made of vis- coelastic material that obeys the fractional deriva- tive constitutive relation. The steady-state re- sponses to simple harmonic excitations are obtained. The effect of the viscoelastic material coefficient on the amplitude-frequency characteristic is discussed.
