Abstract:
This paper studies problematic of a mechanical system composed of different parts mechanically coupled and submitted to a high speed shock.
After a shock, different parts of the system oscillate. If one of them is excited at a particular frequency, such as its proper frequency, important oscillations appear and can lead to the deterioration of the system by introducing important stresses. In this paper, we propose an analysis in order to understand this kind of problem and what we can do to avoid it. Firstly we discuss problematic and we expose the studied system. In a second time, we present model which allows us to understand the phenomenon by carrying out numerical simulations. Then we complete a comparative analysis of different methods of control. Prospects and problematic of real controlled device are studied. Finally experimental set up is described.
