Practical Accelerated Life Testing
Techniques for Product Development
Current new product development
procedures require a Reliability Test as mandatory to evaluate new
products prior to their releases. There are no simple engineering
equations that describe the failure of a Transport Refrigeration
System, sub-systems or components. The proper determination of the
reliability plan is crucial because an erroneous test plan can be
costly and misleading. The main failure modes may be first
established and the life test developed based upon the failure
modes. The purpose of an accelerated life test is to demonstrate a
minimum life in a simulated customer environment. The ALT results in
the real world depend upon the applied stresses and should be well
behaved when the test conditions are not excessive or unusual.
Simple reliability models may be employed to extrapolate the ALT to
other customer conditions.
Key Words: ALT, Electronics,
Vibration, Warranty Reduction
