Integrated Engineering for Optimized Structural Dynamics Analysis 920909

“Noise and vibration are not invented here!”. Undesirable structural dynamic behaviour is normally experienced on final assemblies, by which time the underlying cause of the problem is difficult to solve intuitively. Solving the problems classically involves the partial breakdown of assemblies and the application of various structural dynamics testing and analysis procedures. Preferably, noise and vibration problems should be avoided by designing the product right the first time, by the use of various integrated analysis and testing disciplines, from the component level to the final assembly. Such an approach is referred to, in a broader sense, by trendy themes as concurrent engineering, forward engineering, simultaneous engineering....
This paper analyzes trends in analytical and experimental structural dynamics toward better integration of the various discipline oriented techniques that are currently used. The likely evolutions in structural dynamics analysis and test systems to meet the requirements of more integrated engineering are reviewed. Three approaches on this topic are reviewed:
  1. -1-
    Finite Element Model Validation by Testing
  2. -2-
    Dynamic Fatigue Analysis
  3. -3-
    Acoustic Radiation Prediction
