Automotive Component Vibration: A Practical Approach to Accelerated Vibration Durability Testing

Automotive components must be designed to withstand vibration for many years of service. This paper reviews a method of developing short duration laboratory tests which can simulate many years or many miles of vehicle service. The general automotive vibration environment and proper data analysis techniques are discussed. Recommendations for developing a test specification from field data and for accelerating a laboratory vibration test are reviewed. General vibration test specifications for both chassis and engine mounted components are presented.
