Abstract
The overall goal of this Phase I project is to show the feasibility of using state-of-the-art parameterization tools for shape changes (i.e., volumetric deformation/morphing provided by Sculptor) coupled with a fast FEA tool (i.e., the MAX method) to quickly calculate the dynamic response of the many different shapes necessary for sample-based stochastic vibration analysis of IBRs with blends. The PI's MAX method is the basis for a robust and computationally effective technology for dynamic analysis. The MAX method allows for quick FEA analysis of different blend shapes for statistical investigations. Current state-of-the-art FEA analysis of industrial models, with several thousands of separate calculations (samples) for stochastic investigations, requires prohibitively long computation time for any realistic results. For example, it is not unusual for a single dynamic analysis of a single IBR to require over 10 days of CPU time. In contrast, the MAX method is expected to require only a few seconds of CPU time. The combination of the MAX method and the mesh morphing technology provided by Sculptor will enable the analysis of blends with arbitrary shape.
