Aspects of the mechanical behaviour of fibre armatures
conference paper
In this paper a summary is given of the development of a method to control the initial values of mechanical aspects of a rail accelerator.
The first part concerns the results of a recent series of launch experiments with the multi-fibre armatures. Experiments to study the influence of armature material on the current diffusion are also presented, and show the necessity for a better control of the initial mechanical conditions.
In the second part an analysis of the stress distribution is made using the mechanical finite element code COSMOS/M. A measurement set-up used to determine the value of mechanical parameters of the multi-fibre armatures, and a fibre optic displacement sensor to measure the preload on the armature for controlling purposes is described too.
