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

Research output: Contribution to book/conference proceedings/anthology/reportConference contributionContributedpeer-review


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.
