A steel mass spring system (MSS) has been designed using the Zimmermann method. The impact of speed on the curve radius, cant, stiffness, static and dynamic deflection of the MSS is observed and the natural frequency of the system is calculated. It has been observed that the speed of the train affects the stiffness of MSS and therefore the insertion loss. As the speed of the train increases, the characteristic length of the floating slab track decreases due to which the spacing between MSS also changes. Hence this design of MSS will be effective.
