Steering Pump End-of-Line Quality Test -Noise and Abnormal Sounds

  • Test Object:

    Steering Pumps

  • Application Scenario:

    End-of-Line Quality Test

  • Challenges:

    As NEVs are relatively quiet, abnormal noise from the steering pump can be easily perceived by users, and is considered as a quality defect.

  • Method of Evaluation:

    Noise and vibration test is conducted after the steering pumps are assembled, where SigMA assesses product quality by conducting spectrum and order analyses.
