Assembling Large Scale System Models From Test and Analysis Using Interactive Computing

摘要

System analysis methods, using a building block approach, offer the ability to assemble component dynamic information from various sources and predict performance of a total system before physical prototypes are available. Information on system performance can be used to qualify designs and define component loads. Component designs can be refined using the load information obtained from the system analysis. These methods, often described as "component mode synthesis", have been available since the early 1960's in batch programs, such as NASTRAN. The advent of the super-mini computer has brought computing power closer to the working engineer and made interactive capabilities more feasible. This paper discusses the implementation of system analysis capabilities in an interactive environment. Graphically oriented methods for data entry, verification and results interpretation are presented. Solution methods oriented toward the super-mini computer are also discussed. The potential impact of these new methods on the design process is reviewed.
