Sea- and inner ports are intermodal traffic nodes that play an important role in transportation, especially the transportation of goods. The appearance track defects a harbour railway network has negative impact on safety, cost comfort (for example due to noise emission). analysis data obtained by embedded acceleration sensors, which installed at axle box equipped in-service vehicle, allows for...

Slow-wave instability in a rectangularly corrugated cylindrical waveguide is analyzed. Fields inside corrugation is expressed by a sum of space harmonics satisfying the boundary conditions at the corrugation wall. The corrugation fields are matched to periodic fields outside the corrugation at the boundary of the two regions. Infinitesimally thin annular electron beam is considered including th...

Abstract Track–vehicle severe interaction on track with small curve radius results in rail wear and corrugation, wheel polygonization, which drain considerable resources for grinding wheels re-profiling metro lines. To reduce the damage caused by track-vehicle interaction, paper analyzes reasons leading to then proposes an architecture of a vehicle independently rotating driven directly permane...
