中文摘要：

基于开放式工程与科学计算集成化软件平台 SiPESC,研发了用于多体系统动力学时程分析的一类通用求解算法构架。该构架的核心思想是算法与数据相分离,整个构架由五个基本类及子类组成。本文重点阐述基本类的抽象过程,利用插件技术设计求解器的构架,进一步应用该构架实现了 Newmark 方法,HHT（Hilber-Hughes-Taylor）方法,Generalized α方法,Bathe 方法及祖冲之类 Symplectic 方法等微分-代数方程组（DAEs）求解器的开发。研究工作表明,本文所提出的 DAEs 求解算法构架对多体系统动力学的时程分析具有良好的开放性和通用性,可方便进行各种新的 DAEs 求解算法的动态扩展。

英文摘要：

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.
