Polytec, a leading provider of optical measurement solutions, has announced the launch of its RotoVib product. This innovation marks a milestone in experimental modal analysis and will revolutionize ...

Structural test engineers use modal analysis to understand the dynamic behavior of structures, including airframes, buildings, and automobile frames. Basically, the procedure is to excite the ...

Modal testing of structures with closely coupled modes is a task performed very frequently. On many occasions, structures have modes that possess very similar resonant frequencies. In one such case, a ...

John O'Callahan has written many papers over the years covering analytical model reduction techniques, structural dynamic modification, estimation of rotational dof, correlation of analytical / ...

Many industries in the last decade successfully implemented finite-element analysis as a tool for product development. The success of FEA is now being followed by more widely used motion-analysis ...
