NOISE AND VIBRATION OF RESILIENTLY SUPPORTED TRACK SLABS

An analytical model is developed for the dynamic response, vibration isolation, and sound radiation of a resiliently supported track slab for subway trains. The general relations for response and radiation of the floated slab are considered in conjunction with rail vibration data to predict slab performance. Results show that the slab is a very effective vibration isolator but is a sounding board at low frequencies.
