摘要：In this paper, using system’s dynamic equilibrium equation to determine the imbalance component of calculation acceleration in Wilson-θ integration algorithm, then react to original system as feedback to revise the computational movement state. Two approaches are presented: to revise in lagged time step, it would retain the unconditional stability of original method; to revise in real time, it would be conditional stability in case of θ≥1.37 and Δt . As a contract, the situation of Newmark method is discussed also.
