Abstract:

Reported here are the interim results of a program under the UMTA Urban Rail Supporting Technology Program to develop a basic understanding of urban transit wheel/rail noise generation for application to the evaluation and improvement of wheel/rail noise control devices. The report critically reviews existing analytic models and related experimental findings for the wheel/rail dynamic system and for the three categories of wheel/rail noise generation: squeal, impact, and roar. The limitations found result in recommendations for the remaining work required. A compilation is presented of existing or promising wheel/rail noise control devices, their acoustic and nonacoustic effects. The relative severity of the three noise categories is compared by examining wayside noise data from numerous transit systems and railroads around the world, and by using a scale recommended here for rating urban transit wheel/rail noise, i.e., the peak A-weighted sound pressure level to which the receiver of interest is exposed. Squeal produces the most annoying noises followed closely by impact and roar. Lastly, methodology is presented for assessing the non-acoustic performance of wheel/rail noise control devices. The method is applied to an example in which it is assumed that resilient wheels are installed on all New York City Transit Authority cars.
