降落伞系统动力学的面向对象仿真框架

针对当前降落伞系统动力学仿真中存在的问题,引入面向对象分析方法建立了开放性的仿真框架。框架由模型库、算法库和系统库三部分组成。实现了基元模型接口的规范化和模型库的层次化,提高了框架可扩充性和适应性。框架提供了通过基元模型组合来建立系统模型的机制,可支持针对不同系统、不同应用的仿真工作。利用该仿真框架,完成了某型飞船降落伞系统建模仿真,验证了框架的有效性。

Object-Oriented Simulation Framework for Parachute System Dynamics

In view of the problems confronted during simulation of parachute system dynamics, the paper put forward an opening simulation framework using object-oriented method. The framework is comprised of model library, algorithms library and system library. The standardizing interface of element model and hierarchy of model library is realized, which make the framework flexible and extensible. The framework provides mechanism of modeling by assembling element model, which make it applicable to simulation for different systems and applications. The effectiveness of the framework is validated by a spaceship's parachute system model built on it.
