Abstract
This paper presents a unified command processor system with an integrated data base for flexible mechanical system dynamics. The system is demonstrated using two well established finite element programs, ANSYS and NASTRAN, and two general purpose flexible system dynamics programs, DADS and DISCOS. The command processor system is based on the recently developed Integrated Analysis Capability (IAC). Using the IAC, well established analysis tools can be used to analyze different aspects of physical behavior that are modelled by a variety of mathematical concepts. The paper (1) describes the requirements for an interdisciplinary command and data base management system, (2) explains the process of incorporating finite element and system dynamic programs into the integrated analysis system, and (3) develops a unified data base for flexible system dynamics. The modular structure and the ease with which new modules can be added to the system make it suitable for analysis of a wide spectrum of flexible dynamics problems.
