Tailoring the structural behaviour of a composite gas-filled spring device for a switch in power grids

Abstract

The shortest possible switching times are required to reduce voltage peaks and thus stabilise the power grids in the event of fluctuating renewable energy generation. Gas-loaded springs made of composite materials represent a promising design solution for this. Due to a complex geometry and anisotropic material behaviour, accompanying numerical analyses are required right at the beginning of the development process. In the present study, the deformation and failure behaviour of a composite spring is analysed by means of a parameter study based on a simplified geometry and load case as well as a combination of different materials and fibre angles. Subsequently, suggestions for the design and further development of the composite gas spring are derived.
