Abstract

The Ampelmann system consists of a motion compensating Stewart platform and a telescoping connection bridge, a gangway. The gangway creates a large asymmetric load case on top of the Stewart platform. The purpose of this study is to make the A-type operable for larger gangways by investigating the possibilities to reduce the cylinder forces by improving the Stewart platform for the large asymmetric load case.
