Abstract：Research purposes: This paper discusses the impact of the complex climate environment on the pantograph catenary system of the electrified railway, focusing on the research status and progress of the influence of environmental temperature, crosswind and icing conditions on the dynamic coupling characteristics of the pantograph catenary system. In view of the current research, the research direction and development trend of relationship between pantograph and catenary under complex climate conditions are discussed.
Research conclusions: (1) Combining the dynamic characteristics of the current collection process of the pantograph and catenary, enriching the transmission characteristics of the environment and arc temperature field in the pantograph and catenary system, and deepening the research on the vibration characteristics of the catenary under crosswind and icing conditions. (2) Establish a multi physical field coupled modeling and simulation of the pantograph-catenary system, taking into account the intricate interactions of temperature, mechanical system, fluid, and current. (3) Improve existing detection methods and algorithms, and timely predict and identify faults caused by environmental factors on the pantograph catenary system. (4) Develop devices to suppress contact line galloping caused by crosswind, conduct research on anti-icing and de-icing technologies for the contact line, and reduce the impact of crosswind and icing on the dynamic current collection performance of the pantograph and catenary. (5) The research results can provide reference for the research direction of pantograph catenary relationship.

Key words： pantograph-catenary system climatic temperature crosswind ice coating
