A “New” Method for Vehicle System Analysis 971511

A new procedure for component mode synthesis has been developed where the residual flexibility effects due to modes truncated from the analysis are properly accounted for. Superelement disk storage is minimized in the new method by saving the boundary and transformation matrices only. A special DMAP was developed to save the transformation matrices for data recovery degrees of freedom only. An external superelement is created with a small read only data base. Using this method with a frozen body design, full vehicle models can run on desktop workstations. The number of design iterations that an analyst can do in a given time is increased dramatically in the new method.
