Influence of Track Stiffness on Track Behaviour under Vertical Load
Promet (Zagreb), 2012 The analysis of track behaviour under vertical load is traditionally based on the presumption that the stresses and deformations in track elements can be determined by the application of the Winkler’s Hypothesis.

Quantification of Dynamic Track Stiffness Using Machine Learning [PDF]
IEEE Access, 2022 Railway track stiffness is an essential factor influencing the track conditions and long-term deterioration. However, the traditional ways to measure the track stiffness are based on inverse computations using multi-body simulations and/or finite element

Overview and outlook on railway track stiffness measurement
Journal of Modern Transportation, 2016 Stiffness is one of the basic performance parameters for railway track. The efficient and accurate stiffness measurement has been considered as the foundation for further development of railway engineering, and therefore has great theoretical and practical significance. Based on a summary of the connotation and measurement of track stiffness, the state

A Study on the Evaluation of Track Support Stiffness on the Various Track Type in Urban Transit [PDF]
Journal of the Korean Society for Railway, 2011 Track support stiffness which affected track maintenance and riding comfort had a big effect on the track and train. Also, track support stiffness of the track design which was based on theory differs from track support stiffness of the track generated on the field.

Simultaneous Motion Tracking and Joint Stiffness Control of Bidirectional Antagonistic Variable-Stiffness Actuators [PDF]
IEEE Robotics and Automation Letters, 2022 Since safe human-robot interaction is naturally linked to compliance in these robots, this requirement presents a challenge for the positioning accuracy. The class of variable- stiffness robots features intrinsically soft contact behavior where the physical stiffness can even be altered during operation.
