Trains in tunnels test facility - the influence of model velocity fluctuations caused by rope elasticity on tunnel flow (IM-AERO-116)

The elastic behaviour of Kevlar ropes in rapidly accelerating and then towing model trains at speeds of up to 70 m/s has been investigated, Ref 1. The study shows that if the models are towed by driving the "far" pulley, Fig 1 as proposed by Leafields Engineering the elasticity of...
