Control System

ICF BOGIE SUSPENSION : 

INTRODUCTION : ICF Bogie Suspension refers to the suspension system used in the bogies (wheel assemblies) of Indian Railway coaches, designed by the Integral Coach Factory (ICF). It plays a crucial role in providing stability, comfort, and safety by absorbing shocks and vibrations from the track. The suspension system consists of springs, dampers, and other components that ensure smooth movement, reduce wear and tear, and improve the overall riding experience for passengers. It is a key part of the railway’s efforts to enhance the durability and performance of its rolling stock. 

ABSTRACT : 

The ICF Bogie Suspension project aims to enhance the performance of Integral Coach Factory train bogies through advanced control systems. Focused on improving ride comfort, stability, and safety, the project involves designing and implementing innovative suspension systems. The integration of intelligent control mechanisms, such as adaptive damping and real-time adjustments, is explored to optimize the bogie's response to varying track conditions. Through simulation, prototyping, and rigorous testing, this initiative seeks to elevate the overall train experience. The final output will not only showcase a refined bogie suspension system but also demonstrate its seamless integration into the broader context of train control systems, ensuring a technologically advanced and reliable solution.

TRANSFER FUNTON

X(s) / F(s) = 1 / 5000s^2 + 2000s + 18000

wn^2 = 18000

wn = 134.16

2*zeta*wn = 2000

Zeta = 7.45 (OVERDAMPED SYSTEM)

From Final value theorem

Xss=lim s>0 S.X(s) =lim s>0 S.X(s)/F(s).F(s)

=lim s>0

1/5000s^2+2000s+18000.1/s

Xss=1/18000= 0.0000555556

1. Settling time

2% = 4 T

= 4 / 7.45 *134.16

= 0.004sec

Where, T = 1 / zeta * wn

5% = 3 T

= 3 / 7.45 *134.1= 0.003sec
