Evaluation of Passenger Ride Comfort of Indian Rail and Road Vehicles with ISO 2631-1 Standards Part 1-Mathematical Modelling

Ride quality and ride comfort are the most important performance indices of road or rail vehicles and is affected by various factors, such as vibrations, acoustics, smell, temperature, visual stimuli, humidity and seat design. Among these vibration is a dominant factor that influences the performance indices the most. In this work the coupled vertical-lateral mathematical models of Indian rail and road vehicles have been formulated using Lagrangian. The roadway vehicles considered for this analysis are three wheel and light four wheel Indian passenger vehicle. The rail vehicles considered for this analysis are General sleeper ICF coach of Indian railway.
