What is it about?
Active suspension is a powerful technology that can improve the vehicle dynamic performance and make simplified vehicle concepts possible. The KTH Railway group has, together with external partners, investigated active suspensions both numerically and experimentally for 15 years.The paper provides a summary of our research activities in this area and the most important findings.

Why is it important?
It is difficult to further improve the dynamic performance of rail vehicles with conventional passive suspension. Also, simplified vehicle respectively running gear layouts that significantly could reduce vehicle weights are difficult to realize with modern requirements on passenger vibration comfort and wheel and rail wear. Active suspesion is a good solution to solve these issues.
Perspectives
To our opinion active suspension can give a lot of benefits to rail vehicles. Therefore it was a pleasure for us to write the article and spread some of our ideas to a wider audience.
