Description
The railway transportation system is currently undergoing a significant expansion. As a result, train lines are upgraded, and the technical condition of the rail vehicles that use them is also taken into consideration. However, under certain circumstances, wheels on rail vehicles may sustain damage while in use. The passenger's ride comfort is diminished when a rail vehicle with a damaged wheel is in operation. The research considered one type of railway wheel damage, which is wheel polygonization, and focused on analyzing the ride comfort for passengers based on results obtained from multibody dynamic analyses. The findings demonstrate that with increasing vehicle speed, the ride index also increases. However, running an overloaded carrying capacity vehicle has minimal comfort compared to an empty and rated carrying capacity vehicle when the wheel has a polygonization defect. The study has a significant impact on maintenance planning for wheels as well as operation management.
