Modified Adams-Moulton predictor-corrector method in solving multibody dynamical systems

A modified Adnms-Moulton predictor-corrector method is proposed to solve mu ltibody dynamical systems. The proposed method is obtained by combining an Adams-Bashforth predictor method and an Adams-Moulton corrector method with derived weighting coefficients. With the modification, the accuracy of the proposed method is almost one order of magnitude better than the Adams-Mou lton predictor-corrector method with the same step size. Stability limits o f the proposed method are also studied. Because the present method has grea ter stability limits than Adams-Moulton predictor-corrector methods, the pr oposed method has good robustness during the process of time integration. A crank-slider mechanism is used as an example to investigate the capability of the proposed method in solving multibody dynamic systems.
