Rack feeders are central components
of automated racking systems. The design and the optimisation
of a new feeder were based on results gained from static and dynamic
analyses. Dynamic loading during acceleration, breaking and emergency
stops governed many aspects of the global and detailed design.
Fatigue was the governing criteria for all investigations.
A global parametric study resulted in general design guide lines
giving the highest possible acceleration values for given feeder
height and crane platform loading capacity.
The connection elements between the rack feeder mast and the sliding
carriage on the one hand and the rack feeder mast and the crane
platform on the other hand were analysed in an extensive 3D finite
element analysis.
