Abstract

Railway vehicles have evolved significantly over the previous century, but the suspension mechanism has remained relatively the same. This outdated system needs some testing and validation to improve the working principle of railways vehicles. In this study, simulation software named MATLAB Simulink is used to simulate the railway suspension system. This study presents a secondary suspension system for railway vehicles. The basic concepts of the railway vehicle suspension system and its vibration characteristics were analysed and investigated. The study has compared two different models namely Nishimura and Conventional model. Both models were developed based on Newton’s second law and were simulated in MATLAB simulation software. To simulate the suspension models, sets of parameters have been used for spring and damper. The simulation outputs were evaluated according to the vibration characteristics of the railway vehicle body. This simulation results show that Nishimura is selected as a better model if compared to Conventional and it has been chosen for further findings. It is because Nishimura has lower vibration amplitude over acceleration and displacement compared to the Conventional model. Nishimura model is then used to analyse the vibration amplitude if certain parameters were manipulated.
