Investigation on Advantages and Problems of Air Springs in Railway Transportation

In this paper, we study the history, advantages and disadvantages which are related to thermodynamics issues. Furthermore, the air spring pneumatic diagram of IRICO Rail Bus is presented. Comparison between a conventional wagon with helical springs and a wagon with air springs as secondary suspension is carried out. Two types of springs are modeled and simulated by Adams/Rail. The model analyzed dynamically and the results are used for some main indices such as ride comfort, wear number and derailment
