Abstract：Research purposes: The fittings, mast and support system of catenary play an important role in design of catenary of high-speed railway. Whether its structure is stable or not directly makes effect on the dynamic received current between the pantograph and catenary and it is also one of the key factors of guaranteeing traffic safety.
Research results: With continuous development of railway and continuous increasing speed of train, the computing program with define-element analysis to create optimized computing input and output interface can improve the design efficiency, accuracy and quality of catenary of electrified railway.
