Balancing Speed Simulation
Balancing speed of train is the maximum achievable speed of a loaded train on the level track in normal environmental conditions. Balancing speed of the train is calculated by the intersection of the total resistance-speed curve and the tractive effort-speed curve. Ideally, a train will cover infinity distance to achieve its balancing speed because acceleration of the train never reaches to zero in the traction mode. Practically, when the increment in the train speed on level track becomes less than one kmph in one minute (i.e. acceleration of 1000/(3600*60)=0.004629 m/s2), speed of the train should be considered as balancing speed of the train. Please input the following parameters for calculation of balancing speed :
#Note: Please read Para 'Limitations of online Train Balancing Speed Simulation tool'. This is an online demo simulation tool and results of online balancing speed simulation tool may have some error due to these limitations. However, our offline software tools do not have such limitations and provide much accurate simulation results. For detailed description of technical terms used in this simulation tool, please read 'Technical Terms' & 'Performance Parameters' sections of this website.
A slight variation in train resistance value at higher speed introduces considerable error in balancing speed calculation. If correct values of coefficient 'A', 'B' & 'C' are not entered in train resistance formula TR= A+B*V+C*V2 Kg/ton, it may introduce error in result of Train Balancing Speed Simulation tool. User can not use their specific train resistance formula here.
In this simulation tool, TE vs Speed graph has two quadrant portion only. In first quadrant, TE is inversely proportional of speed & in second quadrant, TE is inverse quadratic of speed. All shapes of TE vs Speed graph can not be developed in this simulation tool.
