A. G. Ramm,G. N. Makrakissearch allowing the computation of blocked forces at car body input points and starting with wheel/rail interaction is briefly presented. Concerning source modelling, a focus is made on traction noise, including electromagnetic excitations in electric motors and mechanical excitations due to the mes

Peter Rejto,Mario Taboadaurve and did not squeal. Other factors, such as speed, rail lubrication and rail grinding, would influence wheel squeal generation when combined with high angles of attack. These factors were found to influence squeal behaviour, but are secondary for controlling wheel squeal compared with solving th

Martin Schechtercted from across the Sydney rail network. This system integrates:.This system enables us to communicate the magnitude of the noise impacts and to track the progress we are making on reducing these noise impacts. This paper outlines how we use this system as a tool to facilitate more effective, effic

V. Yurkotation of the dipole axis needs to be specified. Moreover when more than one dipole is concerned, a special disposition of the dipoles together with a selection of difference in their sound powers can result in a change of directivity pattern from that of a monopole to that of a dipole..Since rail r
