A procedure for validating rigid catenary models using evolutionary techniques
Computers & 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.

A Two-Stage Detection Method of Rigid Pantograph Catenary Contact Points Using DCNNS
Journal of Physics: Conference Series, 2021 Abstract Pantograph catenary contact point is an important monitoring object during pantograph catenary operation, which reflects the state of pantograph catenary operation. However, due to the relatively small contact area of the target area, it is still a challenge to locate the contact point quickly and accurately.
