Curva en espiral para ferrocarril:
Datos iniciales:
PI = 1 + 150
ΔT = 20°
Veq = 60 Km/hr
Vía férrea tipo A
Gc = 3° = 0.05235988 Rad
1.- e = 0.001 (60) 2 (3 ) = 10.8
2.- Le = 0.07 (10.8) (60) = 45.36
3.- Nc = 5
Le = 10 Nc = 50
4.- Rc = 10/sen(Gc/2) = 382.0155001
5.- θe = (50/40) 3 = 3.75° = 0.06544985
6.- Xc = Le ( 100 – 0.0055 θe2)/100 = 49.97539
Yc = Le ( 0.582 θe – 0.00001266 θe3)/100 = 1.09091619
7.- P = d = Yc – Rc (1 – cos(θe)) = 0.27299168
K = t = Xc – Rc(sen θe) = 24.99038088
8.- CLe = (Xc2 + Yc2)^2
9.- D = Rc + d = 382.2884918
10.- St = D tan (ΔT/2) = 67.40777552
11.- TST = Ste = t + ST = 92.39815640
12.- Δc = 20 - 2 θe = 13
13.- Lc = 20(13)/3 = 86.66667
14.- KmTE = KMPI – Ste = 1 + 057.60
15.- KmEC = KmTE + Le = 1 + 107.60
16.- KmCE = KmEC + Lc = 1 + 194.27
17.- Km ET = KmCE + Le = 1 + 244.27
