Study of lateral forces on wheel and rail at the interface between Rahahan and Javadieh stations in Tehran Metro Line 3, using Adams-rail software

The present paper focuses on study of parameters such as lateral force, wagon weight, train speed and those have greatest effects on wear mechanism of wheel and rail. ADAMS-RAIL simulation software was used for dynamical modeling of train while moving via railway. Also, the effects of mentioned parameters were contributed in this simulation. The results shown on curved rail train with weight gain, from least to greatest weight, i.e. 37.5 tons to 61 tons at the same speed, lateral force is significantly increased to 55% but By studying changes in speed can be realized, which increases the speed of the lowest to the highest speed at 25 kilometers per hour to 65 kilometers per hour (equivalent to 7 meters per second to 18 m/s) is about 15 percent less impact on the increase lateral force on the wheel flange and gauge corner of rail . The effect of speed on the lateral force on the wheel flange and gauge corner of the minimum and maximum crest rail at almost half the weight of the train in the same state.
