Track 1 Session 7
1:00 to 2:00 p.m. Thursday March 27, 2008
Combined Test Specifications for
Automotive Products Based on Measured Vehicle Data and Product
Service Feedback
Extensive warranties proposed by
the automotive manufacturer lead the automotive supplier to develop
new test specifications. These specifications should validate the
durability and the design life requirement. This session will
present an original combined test method. Three main stresses are
simultaneously considered:
- temperature
- pressure pulsation
- vibration
The stress levels and the test
duration are defined knowing the vehicle duty cycle and measured
vehicle data. The definition of the pressure pulsation test
specification will be detailed. The test level is determined using
an accelerated law and Miner's rule. Secondly, the validation of the
method will be presented based on product service feedback.
Key Words: Reliability
Testing, Reliability of Automotive Components, Accelerated Testing,
Cumulative Damage, Combined Solicitations, Customer Usage Knowledge
