by Jeff Tuzik A well optimized wheel/rail interface is a quiet wheel/rail interface. In the rail transit environment, there are many technologies and strategies to reduce wheel/rail-generated noise, and they tend to focus on reducing rail roughness. Standard rail grinding, acoustic rail grinding, rail milling, and specialized acoustic grinding machines …
By Jeff Tuzik This article was originally published in Mass Transit (June 2024) in conjunction with the annual Wheel/Rail Interaction Rail Transit conference. In part 1 of this article, a group of experts, including a transit operator, three vehicle manufacturers, and a noise and vibration consultant, examined how to mitigate wheel/rail-generated noise at the …
The article discusses the challenges of vibration and noise in rail transit operations, emphasizing the importance of vehicle design and technology in mitigating these issues. Key design factors, such as unsprung mass and suspension characteristics, significantly impact performance. Strategies from experts and case studies highlight the complexities of optimizing vehicles for noise and vibration control.
