• A new time integration method is proposed, which is a kind of extension of the Wilson-θ method. It has good accuracy, unconditional stability and numerical dissipation. The algorithm and characteristics for linear systems are shown. Also an application method to non-linear systems is described. For analyzing multibody systems, a formulation of elastic link systems consisting two dimensional truss, beam and scalar elements are indicated, and some examples such as a stiff vibration system, a double pendulum system, and a 4-link system are calculated by this method, which demonstrates that it is useful and available to analyzing multibody systems.
