Abstract
The demand for freight transportation is on the rise as a result of population growth, increase in the need for energy, and the expansion of global trade. Existing infrastructure for freight transportation seems inadequate for future growth, and new facilities are required to cover the deficiencies in cargo movement. Underground Freight Transportation (UFT) is a new mode of transportation that uses the space below the ground to carry cargo within autonomous vehicles in tunnels and pipelines. Different propulsion systems have been used for freight pipeline systems. The goal of this research is to find the proper propulsion system for the UFT system. In addition, this research aims at finding the minimum power of the propulsion system and energy consumption for the UFT system operation. Two short-haul and long-haul UFT systems with different load sizes are used to test and apply the results of this research. The findings of this research suggest that because of its light weight and short thickness, a Linear Induction Motor (LIM) is an appropriate propulsion system for UFT. Besides, this research estimates that the energy consumption and power requirement of a LIM system is low. The energy consumption of LIM system is calculated as a function of UFT system operating speed. Therefore, the results of this research can be applied in the design, operation and cost estimating of other UFT systems.
