Posted by Fulton Frank on Tue Jan 4 12:02:10 2005 Hi, one project I'd like to do between terms now is caculate how high a train's outter wheel climbs up its flange when rounding a curve. For this I'd need: the diameter of a wheel (I believe 32" is correct) and also the outside diameter of the flange. The angle of the flange chamfer is important too although i could estimate it. And finally what is the minimum radius of curvature of the tracks on the system - is this measured to the inside or outside rail (probably a small correction anyway). With all this I think one can get a pretty estimate of the maximum alawable speed is for a given curve. Thanks for your help. |
