Research on track damage identification based on the response of vehicle-rail contact point
Transportation Engineering, 2022 In this paper, spring element is used to simulate the vertical support of ballast and sleepers to the rail, which is called “elastic support”. Low-pass filtering technology was adopted to extract the response of the driving frequency component in ...

Vibration and Noise Analysis and Experimental Study of Rail Conveyor
Sensors, 2023 The rail conveyor is a new type of energy-saving system for the long-distance transportation of bulk materials. Operating noise is an urgent problem that the current model faces. It will cause noise pollution and affect the health of workers.

Experimental Study on Settlement Behavior of Ballasted Tracks with Polymer Compound-Coated Gravel
Applied Sciences, 2022 The ballast used in ballasted railway tracks transmits load from the rails and ties to the subgrade during train travel, and directly affects the overall track support performance and elastic behavior of the ballasted track.
