ISOTENSOID PRESSURE VESSELS BASED ON NON-GEODESIC ROVING TRAJECTORIES

摘要

In this paper we evaluate the effect the application of non-geodesic trajectories has on the geometry and performance of composite pressure vessels. This evaluation is based on two cases: firstly we apply non-geodesic trajectories on a meridian profile that is determined according to geodesics and explore the consequences of this application for the mechanical performance while assessing the obtained flexibility for the minimum and maximum vessel radius. Secondly, with the aid of maximum-friction-utilising non-geodesics, we derive the optimal meridian shape providing equal fibre forces at every place belonging to the vessel. While having slightly enlarged design possibilities, the principle of isotensoid fibre loading is here still valid.
