Research Abstract |
The first successful result is the development of a newly innovative intelligent navigator system that can inform the best excitation point on test structure in vibration testing with the minimum effort of additional measurement. The testing is very important to find out the dynamic characteristics of mechanical structures. The reliability and accuracy of structural dynamics identification has been improved by integration of the navigator, modal testing and identification methods. The second successful result is the invention of a new algorithm for rigid-body property identification which is also very important as well as dynamic property. The invention has remarkably improved the identification accuracy. A prototype system was developed and the accuracy improvement was verified.
