A Novel Deployable Emergency Bridge

Abstract:

This paper explores the design of a new type of deployable bridge system composed of a scissor-like deployable element, the walking-slab, the joint, sleeve-pole,cable and lock-device, driving cable etc. Both geometric principles and dynamic analysis are discussed. Then, a 2-m scaled prototype is developed, which was then experimentally tested for dynamic properties. Finally, the results of experiment are in good agreement with the dynamic analysis prediction, which validates the efficiency of the design for the deployable bridge. The primary novelty is scissor-like element of the deployable emergency bridge, which is found to enhance the stiffness of the entire deployable to overcome the natural or artificial barriers.
