Rolling resistance of the wheel tested was found to be a function of slip angle, normal load, and inflation pressure for the soil condition tested. A linear relationship existed between the rolling resistance and slip angle, where the coefficients were found to be a function of inflation ...
As a result of applying quasi-static three mass model method, it was confirmed that the maximum pressure-ward rolling moment was amounted up to 40 % of the sustaining rolling moment of the EMU-320 train when driving at 400 km/h in the tunnel of Honam High-Speed Railway....
Outcome Measure: Each participant performed 3 stationary wheelies of 60 s duration using a wheelchair equipped with an instrumented wheel. Two force platforms were used to calculate the displacement of the center of pressure (DCOP). Results: Median group DCOP amplitude in the anteroposterior axis ...

Numerical results indicate that the action behavior between a wheelset with worn profile and track is greatly different from that of wheelset with coned profile and track under the same moving condition of wheelset. The present results are very useful in further study on wear, rolling contact ...
This photo taken on May 22, 2024 shows a "light-out" factory of Baosteel in east China's Shanghai. (Xinhua/Gong Bing) Walking into the cold-rolling workshop at Baosteel in Shanghai is like entering a dark steel jungle. The "AI brain" supports the main control room with only three ...

The interaction of the wheel and the rail is the physical basis for the movement of rolling stock on railways. In order to reduce the wear rate of wheel sets and rails, it is necessary to create a mathematical model for the interaction o... A Buynosov,E Timukhina,B Argannikov,... ...

Depending upon the nature of the surface, the propelling force acting on the turned steering front wheel could result in an increase in forward rolling resistance. This would be sufficient to explain the differences found in total force. In light of the results from straight running, it was ...
