The design and performance estimation of air springs for the suspension of Maglev

The performance of secondary suspension is one of the most important characteristics of railway vehicles in the regard of vibration and riding comfort. For this reason, the suspension shall be designed to absorb vibration energy effectively and to avoid the resonance which would be occurred by the vibration of the bogies in driving. The main factor of characteristics of suspension is spring coefficient of air spring, and this paper shows how to achieve the desired coefficient and the results of the tests of new air springs.
