STATISTICAL VALIDATION OF STRUCTURAL DYNAMICS MODELS

摘要

There is an increasing reliance in the engineering community on the use of mathematical modelsrnto characterize physical system behavior. This is happening even though, for a number of reasons,rnmathematical models practically never simulate real system behavior perfectly. Because of this reliancernwe require objective, well-founded mathematical techniques for model validation. This paper develops arnformal approach to the validation of mathematical models of structural dynamics systems. It uses arnprobabilistic/statistical approach to the characterization of an important measure of behavior of dynamicrnsystems subjected to random excitations, and seeks to validate a mathematical model in a statisticalrnsense. An example is presented.
