On the automatic selection of reanalysis techniques in machine tool structural element optimization

Structural reanalysis technique methods are employed in structural optimization to analyze new designs efficiently using previous information. In this paper, an algorithm is developed to automatically select proper reanalysis techniques for efficient and accurate analysis during the machine tool structural element optimization process, This algorithm provides an error estimator to control the solution accuracy and a reanalysis capability to eliminate the problem dependency of using a single reanalysis technique. An example is used to demonstrate the advantage of this algorithm oyer the complete (exact) analysis or single reanalysis technique.
