An investigation into the causes of squats—Correlation analysis and numerical modeling
TL;DR: In this paper, a correlation analysis is performed based on measured data and field observations, and then a relation between squat occurrence and some parameters of the vehicle-track system is identified.
Journal ArticleDOI
Axle box acceleration: Measurement and simulation for detection of short track defects
TL;DR: In this article, the track technical state can be assessed with the aid of axle box acceleration measurements, which can indicate short track defects like squats, welds with poor finishing quality, insulated joints, corrugation, etc.
Journal ArticleDOI
Automatic detection of squats in railway infrastructure
TL;DR: In this article, an automatic method for detecting railway surface defects called "squats" using axle box acceleration (ABA) measurements on trains is presented. But the method is based on a series of research results from their group in the field of railway engineering that includes numerical simulations, the design of the ABA prototype, real-life implementation, and extensive field tests.
