In order to understand pantograph performance on domestic high-speed test EMUs, pantograph mechanical and structural strength was anticipated. Pantograph body and base finite element analysis model of test EMUs was built, and pantograph body parts mechanical and structural strength parameter and stress distribution of base and welded seam was analyzed at 600 km/h speed, as well as structural strength of pantograph body, base welded seam and fixed bolt was checked. Result of analysis showed that the test EMUs pantograph body and its installation structural strength was in the safety factor range, which met the requirements of high-speed test train.
