Objectives:
The project is focused on designing and developing complex equipment for vibratory stress relief by using the GMM (Giant Magnetostrictive Material) intelligent material, carrying out the intelligent, fast and accurate control of vibrations, leading to the fast and efficient stress relief of the metallic part, homogenizing rapidly the remanent stress.
The main objective of the project is the identification of those connections from the interdisciplinary field which make possible taking over peak conceptual or technological achievements from other technique sectors, in order to get the increase of technical level for electrical equipment, the increase of efficiency and decrease of energy consumption, the environment preservation.
The strategic objectives of the project are:
-achieving a technological network integrated in the field of vibratory stress relief, which should allow setting up a research center for international cooperation (doctorate, master degree, post-university courses), offering the necessary framework for interdisciplinary research with a view to integrating in European technological platform;
-attracting and forming young graduates with a view to integrating them in research activities;
-publishing papers, books and participating in international conferences with a view to preparing the partnership for FP7

Potential users:

Companies having as activity field the manufacture of welded metallic structures with large and average dimensions.

Technical, economic and social impact:
Technical impact
Vibratory stress relief is a method which treats the metallic parts with accurately controlled vibration energy, solving the problem of gradual dimensional changes and deterioration of mechanical properties of the parts, caused by remanent stresses.
The project is focused on the development of complex vibratory stress relief equipment, by using GMM (Giant Magnetostrictive Material) intelligent material, achieving the accurate control of the vibrations, having as result the efficient and fast stress relief of the metallic part. The electric control system, which has as function the automatic sweeping and analysis of resonance peaks, will be controlled by a computer. By means of its implemented software, it will be able to record automatically the process parameters (frequency, accelerations, absorbed power) and to supply reliable proofs for assessing and inspecting the vibratory stress relief effect.
Economic impact
At present, the stress relief of metallic parts with average and large dimensions is achieved by thermal method. This high energy consuming technology is a polluting and low efficient one
Social impact
By achieving this project, the conditions for setting up a technological network integrated into the field of vibratory stress relief are created, allowing founding a research center for international cooperation and attracting and forming new graduates for the research activity.
