Abstract
This paper presents work in progress toward the development of a test and evaluation system for a new concept in experimental structural dynamics. Structural imaging is composed of both the static and dynamic image of the structure, resulting in the structure’s profile and dynamic response. Structural imaging is realized by interfacing a scanning laser velocimeter to an engineering workstation for data acquisition, signal processing, data modeling and scientific visualization. A software system is to be developed that will allow the investigation of the science and the rapid-prototyping and evaluation of new methods.
The design goals for the system software are presented. The concepts defining the elements of the software architecture are also discussed. The event driven finite state machine is explored as the fundamental model of the system architecture. Run-time configuration of the software and virtual instruments provides a mechanism for the evolution of the system. The concepts of the project and test objects are introduced to support the testing of structures. Issues of systems integration and system objects for handling errors and files are also discussed.
