Iterative generalized-α method for the dynamic analysis of flexible multibody system

The parallel iterative method was proposed for flexible multibody dynamic equations. With the proposed method the index-1DAEs were treated. Such systems are frequently encountered in flexible mechanism dynamics. The new dynamic iteration process has been developed, which it is a considerable improvement over the waveform relaxation algorithms. The inner-outer step parallel iterative process has been raised, and further proved the convergence of the iterative algorithm, as well as the error estimate has been accomplished.
