Abstract
The article gives an account of the results of the construction of mathematical model of the wagon rolling down the hump profile under the impact of the fair wind. There have been derived analytical formulas for determining wagon rolling speed and distance travelled down the first profile hump section. The results of the research obtained can be used for all the rest hump sections with the allowance made for the specifics of braking forces on these sections.
Key words: Speed and direction of fair wind, DAlembert principle, rational function integral and integral containing trigonometric function, speed of wagon rolling down the first profile hump section, distance travelled. .Received: March 4, 2014 Accepted: April 12, 2014 Published: April 30, 2014
