Stability is a key factor for the operation safety of railway vehicles, while current work employs linearized and simplified wheel/rail contact to study bifurcation mechanism assess stability. To stability characters under real nonlinear contact, fully parameterized vehicle wheelset model built. In modeling, geometry nonlinearities wheel rail profiles come from field measurements, including rol...

The study objective is to examine new methods of restoring the axis neck locomotive driving wheel. To achieve goal, task was set and solved reduce hydrogen concentration in during its manufacture repair by means appropriate technology. fulfill this task, following research are carried out, that vacuum thermal exposure, wear determination, diffuse siliconization, definition concentration. scient...

Purpose: Measuring is an important process for finding any physical quantity values. Any measurement primary requirement accuracy. Processes are being replaced, improved and automated gradually. Geometric parameter has become one of the most popular processes in all industries. With its improvements, first achievements have begun. The development usage remote measurements to determine wheelset ...
