基于有限元的主、被动一体化振动控制软件设计

尽管主、被动一体化振动控制的研究已开展多年，具有工程意义的软件化工作还很少。本文制定了一体化振动控制软件的设计方案，为使软件具有处理大型结构的能力，将通过有限元分析软件ＭＳＣ／ＮＡＳＴＲＡＮ引入到软件系统中作为结构分析建模的基础模块，并编制了用于软件进一步开发和功能测试的软件原型系统。以算例说明了软件的工作过程。

PROGRAMMING OF THE INTEGRATED PASSIVE AND ACTIVE VIBRATION CONTROL SOFTWARE BASED ON FINITE ELEMENT MODEL

Although approaches for the integrated passive and active vibration control (IPAVC) have been found in a lot of literatures,the program which can be used in pracitial engineering is still in short.In the paper,as the first step in design of the complicated program,a scheme for IPAVC is developed and a prototype system is coded.The famous finite element program MSC/NASTRAN is adopted as one of the important modules of the software to deal with the latge and complicated structures and sysems.An example is given to show the running process of the prototype system.
