| Abstract: |
| Based on the open software integration platform for engineering and scientific computation SiPESC,a new class of general algorithm framework for dynamics equations of multibody systems dynamics is constructed.The core idea of the framework is that data model class and algorithmic class are designed separately.The whole framework includes five basic classes and their subclasses.The abstract process of the basic classes is focused on,and the development process of the framework is given by employing the software plugin technology.Furthermore,Newmark,Hilber-Hughes-Taylor(HHT),Generalized α,Bathe and Zu Chongzhi Symplectic method are implemented.This investigation shows that the framework has favorable extensibility and openness which is common to algorithm of general time-history analysis for dynamics equations of multibody systems dynamics. |
