    • Abstract
  • In this paper the nonlinear responses of a forced TDOF structure are investigated. There are some highly nonlinear and coupling terms in the motion equation of the system. Firstly, the responses of the system to deterministic excitation are calculated by the Re-cursive-digital-Filtering-Technich (RDFT). Then the responses of the system to random excitation are calculated by the Simulation Method based on RDFT and the Ito's Calculus-cum-Si-mulation-Method (ICSM).The results show that the ICSM is more efficie...
