N2 - The high-speed electromechanical transmission(EMT) system for vehicle is characterized by a highly compact structure and high-speed components,leading to significant electromechanical coupling effects and susceptibility to resonance. This paper analyzes the electromechanical coupling inherent vibration characteristics of a series EMT system. An inherent vibration model of the system is derived, its natural frequencies and mode shapes are studied, and six typical vibration modes of the system are summarized based on the characteristics of each mode shape. The influences of high-speed operating conditions and electromechanical coupling effects on the system's natural frequencies and mode shapes are investigated. The resonance speeds of the system within a wide operating speed range are studied using Campbell diagrams and modal energy method. The results indicate that the electromechanical coupling effects alter the low-frequency vibration characteristics of the system, and the high-speed operating conditions can significantly change the certain natural frequencies of the system. Both factors should be fully considered in dynamics modeling. The research of resonance speed provides a reference for the dynamic regulation and optimization of system.
