摘要：The Maintenance Robot with Charged is used in substations which voltage level is under 220kV. The Robot mainly performs electrified maintenance work on pillar insulators and other equipment in substations. There are many equipments in the substation, the magnetic field distribution is not uniform, and the influence of the power frequency magnetic field on the robot cannot be ignored. Statics and modal analysis with the method of finite element of the robot's mobile chassis under idle speed are carried out according to the structural characteristics and walking characteristics of the robot combined with the frequency characteristics of the power frequency magnetic field in the substation, and then the stress distribution, low-order frequencies and corresponding mode shapes of the robot's mobile chassis under idling condition are obtained, and the influence of the power frequency magnetic field in the substation on the dynamic characteristics of the robot was analyzed based on the simulation results.
