Research on comprehensive load vibration test of electric vehicle motor controller unit

In this article, the vibration test standards and general methods for electric vehicle motor control unit are introduced. New conditions proposed based on data collected during actual test. Using output current as electrical load of controller unit, temperature cycle environmental load, a comprehensive method that integrates is proposed. According to method, equipment process on-load determined. Summarized three important principles in design fixtures: lightweight, low damping, no resonance. A novel testing controllers
