Evaluation of Spring Stiffness of Resilience Pads for Booted Sleeper Track System Using a Pressure Sensor

To date, the spring stiffness of resilience pads was mostly evaluated based on conventional (site measurement and laboratory tests) methods. Most studies in past analyzed effects deterioration track damage. examine pads, evaluations were conducted tests using site measurements samples collected from site, or loading special equipment. such as TSS. However, no methodology proposed to prove theoretical equations Zimmermann which compute reaction force at rail support point. Hence, this study aimed that increased if point increased; achieved by a pressure sensor according Zimmermann. Furthermore, we propose method evaluate predict extent increase measured sensor.
