Abstract

Vibration tests of a pure electric vehicle were conducted, modal frequency alignment was given, a comprehensive grasp of the vibration characteristics were shown, including order characteristics of motivation and their transmission paths, transient vibration and vehicle comfort evaluation problems. The vibration problems appeared in the test were summarized, incentives characteristics and amplitude values were compared between the traditional vehicle and the electric one. The conclusions can be used in the electric vehicle’s vibration problem solving, and provide experiment guidance in related system improvements.

Key words
