Dynamics of Partial Space Elevator with Parallel Tethers and Multiple Climbers

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 622)

Abstract

This paper proposes a novel concept of partial space elevator with parallel tethers and multiple climbers. The parallel tethers impacting on the dynamic response of partial space elevator is investigated based on a high-fidelity and accurate model of PSE. The model is developed based on the nodal position finite element method in the arbitrary Lagrangian–Eulerian description. The results show that the tethers collide when the transient motion of climbers is not the same, such as the movement direction of climbers is opposite and the time delay between climbers. It also found that the multiple climbers of each other may aggravate the libration motion of PSE without predesigned time shift. The results show the trajectories of climber are very important and should be well designed to avoid the collision of tethers and assure the safety operation of load transfer.
