• Resumen

  • Viscoelastic oscillator (VEO) is the basic model extracted from viscoelastic damping structures. To precisely understand the dynamic behavior of VEO, generalized modeling of fractional viscoelastic oscillator (FVEO) is proposed and its frequency response is deduced. For demonstrating purpose, frequency response of three FVEOs is studied. As an engineering application case, the viscoelastic suspension mounted in a heavy crawler-type vehicle is considered and its vibration model is built by FVEO, whose time-domain solution is numerically derived by matrix differential theory. The results indicate that FVEO is a valid approach to evaluate the dynamic response of viscoelastic damping structures.
