Dynamic amplification factors for ultra-high-speed hyperloop trains: Vertical and lateral vibrations

Dynamic amplification factors for ultra-high-speed hyperloop trains: Vertical and lateral vibrations

The ultra-high-speed (UHS) Hyperloop is the next-generation mode of passenger/freight transportation, and is composed of a tube or a system of tubes through which a pod travels free of friction. The entire system must be supported by piers (multi-span viaducts), where the tubes act as the bridge deck. The UHS moving Hyperloops can exert large dynamic effects to the supporting pier-deck system both vertically and laterally. Particularly, asymmetric Hyperloop loading can generate significant lateral vibrations. Therefore, for safe design of a bridge pier-deck system for UHS trains, it is of great importance to explore dynamic interaction of bridge deck and piers under UHS moving Hyperloops. Hence, this paper analytically summarizes the dynamic amplification factors of the Hyperloop-deck-pier system for vertical and lateral vibrations. It was found that the UHS Hyperloop trains result in higher dynamic effects compared to the high-speed trains.

Abstract

The ultra-high-speed (UHS) Hyperloop is the next-generation mode of passenger/freight transportation, and is composed of a tube or a system of tubes through which a pod travels free of friction. The entire system must be supported by piers (multi-span viaducts), where the tubes act as the bridge deck. The UHS moving Hyperloops can exert large dynamic effects to the supporting pier-deck system both vertically and laterally. Particularly, asymmetric Hyperloop loading can generate significant lateral vibrations. Therefore, for safe design of a bridge pier-deck system for UHS trains, it is of great importance to explore dynamic interaction of bridge deck and piers under UHS moving Hyperloops. Hence, this paper analytically summarizes the dynamic amplification factors of the Hyperloop-deck-pier system for vertical and lateral vibrations. It was found that the UHS Hyperloop trains result in higher dynamic effects compared to the high-speed trains.
