| Resumo: | The problem of loss of adhesion between rails and vehicle wheels has always
been present in rail transport, which can make travel unfeasible in unfavorable
situations. Since the 19th century, so-called sandbox systems have been used, whose
function is to expel sand or other abrasive materials in the vicinity of the contact surface
between the wheels and the rails. The fleet of Light Rail Vehicles (LRVs), inserted in
Natal in 2014 by the CBTU, however, does not have sandboxes, which is a problem
especially on rainy days. In this context, the present work aims to design a sandbox
system for CBTU-Natal’s vehicles, addressing its operation, materials, costs,
dimensioning and installation. This work deals with an initial proposal for the
implementation of sandboxes in CBTU-Natal fleet and needs continuity in the more
detailed survey of costs, component manufacturing processes, dimensioning and
insertion tests in the LRVs. As a material for the sand container, the present proposal
suggests polycarbonate (PC) due to its chemical stability, excellent mechanical
properties, transparency and low density. For the compressed air outlet system and
sand flow channel, the use of aluminum alloys is suggested due to their low density,
low cost, low porosity, resistance to oxidation and ease of work, with emphasis on the
binary Al-Si and ternary Al-Mg-Si. |
