查询词典 safety rail

Focusing on severe wheel flange/rail side wear and a series of derailments of tramway vehicles with independently rotating wheels, an investigation has been carried out by comparison against solid wheelsets. Based on MATLAB/SIMULINK and a self-developed simulation model considering the IRWs, derailments have been simulated with results of possible causes of such derailments. Efforts have been made to fulfill comprehensive treatment of controllable factors such as the wheel profile, lubrication, clearance between check rail and high rail etc.
