The preload-dependent dynamic stiffness of a primary suspension isolator on a high-speed tilting bogie is examined via measurements and modelling within an audible frequency range. The stiffness is found to depend strongly on both frequency and preload. The former displays some resonance phenomena, such as stiffness peaks and troughs, while the latter exhibits a steep lowfrequency stiffness increase in addition to an anti-resonance peak shifting to a higher frequency with increased preload. The problems of simultaneously modelling the preload and frequency dependence are removed by adopting a frequency-dependent waveguide approach, assuming incompressible rubber with an Abel operator kernel as its shear relaxation function. The preload dependence is modelled by a non-linear shape factor based approach, using a globally equivalent preload con®guration. All the translational stiffnesses are modelled, including the vertical, longitudinal and lateral directions, and the vertical stiffness results are compared to those of measurements in a specially designed test rig. Good agreement is obtained for a wide frequency domainÐcovering 100± 600 HzÐusing a minimum number of parameters and for a wide preload domainÐfrom vanishing to the maximum in service, 90 kN.

“…A recent review of modelling methods for railway vehicles is presented in reference [9] and for advanced ground vehicle suspension systems in reference [10]. However, the suspension system is often found to be too complex to be analysed theoretically [11]. A direct approach to the problem is through a non-linear ®nite element method [12].…”

“…In contrast, the prediction of noise radiation by wagons remains poorly developed. Therefore, as part of the Brite-Euram project Silent Freight, both modelling [3] and experimental methods have been investigated to improve this situation. In this article research on experimental analysis is presented.…”
