The invention relates to a railway electrification catenary in a strong wind environment and a parameter determination method thereof. The strong wind in the wind area and tuyere will cause greater and more complex vibration and wind deflection of the catenary, which will affect the dynamic quality of pantograph-catenary operation and threaten the safety of pantograph-catenary contact and catenary structure. The invention comprehensively adopts CFD numerical simulation calculation, catenary wind-induced response finite element analysis, pantograph-catenary simulation, wind tunnel test and field engineering test, and proposes structural strength, stiffness, reliability, wind resistance stability and pantograph-catenary dynamic flow performance A well-integrated catenary, that is, adopt a structure height of 1100mm, a span of no more than 50m, a proper match between the tension of the catenary cable and the tension of the contact line, the overall steel arm structure, the conversion column and the turnout column as double arm columns, the contact line and the contact line A simple chain suspension system anchored by catenary cables. The invention proposes a catenary adaptable to strong wind conditions, which ensures the safety and reliability of the catenary structure under the action of long-term strong winds.
