Abstract

This paper presents a new mathematical model for the Aeromovel transport system, which is a non-conventional Automated People Mover (APM) based on pneumatics. The vehicle runs over rails installed on an elevated guide, being propelled by air that is pressurised by means of an external power source (a blower) installed on the ground. The proposed lumped-parameter model is intended as an auxiliary tool for the development of this technology, especially in what concerns its trajectory control algorithms. The dynamics of the pressures in the chambers of the actuation pipe are modelled with basis on energy and continuity assumptions, and important phenomena, such as air compressibility, leakages, and steady-state head losses, are taken into account. The model is validated by the comparison between results of simulations and direct measurements performed in a real-scale prototype constructed in Porto Alegre, Brazil.
