Monitored the metro trains before the official launch of Olympic line at Rio de Janeiro with the use of a PolyU-developed optical fibre sensing technology

The PolyU team took on the mission to scrutinise the trains operating in Rio de Janeiro metro lines before the Rio Olympics 2016. They made use of the PolyU-developed optical fibre sensing technology to conduct a comprehensive monitoring on the dynamic performance of the critical components (such as acceleration, strain and temperature) of motor and trailer cars, covering bogie, axle box, lifting plate, gear box, antenna beam and traction. The team also conducted a 4-day on-board monitoring for a cumulative mileage of 500 km, in accordance with industry standards.This 16km long metro line served to carry Olympic athletes and spectators commuting between downtown Rio de Janeiro and the Olympic Village at the time of completion, with a maximum speed of 100 km/h and a capacity for 2,240 passengers.
