Dynamic Characteristics Analysis of Double Pantograph Catenary of AC Rigid Catenary System
IEEE Access, 2023 The Euler-Bernoulli beam theory is used to establish the vibration differential equation of the rigid catenary, the cantilever support device is equivalent to the spring, and the pantograph is equivalent to the three mass block model.

Defect Diagnosis of Rigid Catenary System Based on Pantograph Vibration Performance
ActuatorsThe condition of a catenary is significant to ensure a high current collection quality. Owing to the dynamic interaction between the pantograph and the catenary system, the vibration of the pantograph can be used to analyze the condition of the catenary ...

A procedure for validating rigid catenary models using evolutionary techniques
Computers and Structures, 2020 This paper describes a method to validate rigid catenary finite element models from modal tests. The model parameters are obtained by means of an optimization process using evolutionary techniques. The validation of rigid catenary sections is a complicated process due to the large number of parameters to be tuned.

Contact Loss Simulator to Analyze the Contact Loss of a Rigid Catenary System [PDF]
Journal of Electrical Engineering and Technology, 2017 In this paper, a contact loss simulator for a rigid catenary system was designed and used to analyze the effect on the power source according to the conditions of the rigid catenary system and pantograph. R-bar applied to a high-speed train among the real rigid catenary system was used in the contact loss simulator for rigid catenary systems.

Characterization of the Dynamic Behavior of Transition Systems between Rigid and Flexible Catenary
2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019 The study presented will deal with the dynamic behavior that exists before the transition that occurs at the entrance and exit of a tunnel when a rigid catenary has been installed in the latter while flexible catenary systems are maintained abroad. The transition beam used is an element that aims to mitigate the dynamic differences in the strength of ...
