A Hybrid Design Optimization Method Using Enriched Craig-bampton Approach
A hybrid design optimization method is presented which combines a number of techniques such as Component Mode Synthesis (CMS), Design of Computer Experiments and Neural Networks for surrogate modeling with Genetic Algorithms and Sequential Quadratic Programming for optimization. In the method, the FE analysis is decomposed and reduced by a well-known CMS technique called the Craig-Bampton metho...
متن کاملDual Craig-Bampton with enrichment to avoid spurious modes
The dual Craig-Bampton method can suffer from the fact that the reduced system has negative eigenvalues. Those negative eigenvalues are related to modes with weak interface compatibility and can be present in the lower frequency range when the reduction space is too poor. In this paper we investigate is so-called Modal Truncation vectors related to the interface forces can be used in the reduct...
متن کاملExperimental Based Substructuring Using a Craig-Bampton Transmission Simulator Model
Recently, a new experimental based substructure formulation was introduced which reduces ill-conditioning due to experimental measurement noise by imposing the connection constraints on substructure modal coordinates instead of the physical interface coordinates. The experimental substructure is tested in a free-free configuration, and the interface is exercised by attaching a flexible transmis...
متن کاملCraig Thompson: The method to cancer's madness
C ancer cells proliferate with abandon and in defi ance of the restrictions usually placed on dividing cells. How do cancer cells—or normal dividing cells, for that matter—fuel rampant growth? That's a question Craig Thompson is bent on answering. Thompson trained in research while serving as an MD in the US Navy (1). Though he never went to sea, he has made waves throughout his career—fi rst a...
متن کاملAn enhanced splined saddle method.
We present modifications for the method recently developed by Granot and Baer [J. Chem. Phys. 128, 184111 (2008)]. These modifications significantly enhance the efficiency and reliability of the method. In addition, we discuss some specific features of this method. These features provide important flexibilities which are crucial for a double-ended saddle point search method in order to be appli...
