Potential for tunnel technology in the development of hyperloop vacuum rail

Hyperloop is a new concept of transport system the main assumption of which is to use hermetic tunnels where air pressure is very low compared to atmospheric pressure. It enables significant reduction of traffic resistance and, as a result, energy consumption. One of the most important elements of this system is land infrastructure with transport tubes. This system component has a significant impact on the construction costs related to the whole system and affects its functional parameters (e.g. capsule travel speed). Appropriate configuration of the route of a new transport system will require the use of all possible ways of leading transport tubes, including tunneling. The paper presents the key premises that prove a large potential application of tunnel technologies in the development of a new transport system.

Due to the innovation of transport means based on hyperloop technology, the correctness of its functioning should be investigated in relation to many technical, economic and operational factors. This paper presents an analysis of the hyperloop technology from the point of view of ensuring safety of passengers while travelling in a low-pressure rail tunnel. The main subject of research was the design of hyperloop station infrastructure and the safety management system that will ensure the safety of passengers at the station in the sphere of atmospheric pressure, despite the station’s interaction with low-pressure tubes during entry and exit of the capsules. The safety management system also includes evacuation of passengers from low-pressure tubes in an emergency situation. The paper reviews the key issues of passenger safety in the hyperloop transport system, which are the source of justified and unfounded people’ fear of using this transport means despite its obvious advantages. The authors’ original achievement is the identification of critical points of passenger safety during their stay in the station area and during their journey through a low-pressure tunnel, as well as the design of a double airlock that can be used in the hyperloop tunnel at repeatable intervals with the aim of evacuating passengers to the atmospheric pressure zone. The designed solution allows to eliminate one of the significant weaknesses of the transport system using low-pressure rail.

Analysis of the vibration measurement and reduction possibilities in linear infrastructure for vacuum rail technology

The paper presents the concept of vibration measurement and reduction system for rails in hyperloop technology. It is based on the experience of measuring vibrations in high-speed rail, the first commercial magnetic rail, and vibration reduction systems for these rails. The authors outlined a conceptual vibration monitoring system based on the MQTT protocol and the vibration reduction method. The vibration reduction systems based on variable-characteristic silencers and solutions used in research centers, especially in CERNie and LIGO, were de-scribed.
