| Outline of Final Research Achievements |
We have developed a new model which can analyze the vibration characteristics of a bolted joint quantitatively, when changing the axial tension of the bolted joint from the minimum to the maximum in tolerance level. In order to apply to industrial application based on the basic research of the new bolted joints in which axial tension can be controlled.
The following research items are carried out.(1) We investigated modeling of the new bolted joints in which axial tension can be controlled, development of an analysis system, and identification of the parameters. (2) We made it in agreement of vibration characteristics for various structures by controlling the axial tension of the new bolted joint. (3) We studied the method of controlling the vibration characteristic of structures. (4) We applied to the complicated structure including the new bolted joint. And we developed control method of the vibration characteristics of structure.
