Gravity Calculation Format for China Railway:
H = (Q wagon*H wagon+ Q cargo*H cargo+...) / (Q wagon + Q cargo+...)
Q wagon : wagon net weight
H wagon: center of gravity of wagon
Q cargo: cargo gross weight
H cargo: center of gravity of cargo + wagon height
(H should be less than 2000mm)
Reinforce Calculation Format of China Railway
Reinforce Calculation Format of China Railway:
Q1 = [Q2 X (H-2000)] / (2000 - h1)
Q1 : weight of the ballast
Q2 : wagon net weight + cargo weight, t
H : wagon center of gravity of wagon before putting ballast, mm
h1 : the height from the center of gravity of ballast to the railway, mm |
