The Strategy of Accelerated Reliability Testing Development for Car Components

This paper analyzes the reasons why current accelerated reliability testing (ART) results for passenger cars often cannot give accurate information for sufficient reliability, fatigue, and durability evaluation and prediction in the field. Why does accelerated testing (AT) give often minimum benefits for companies that use it?

The basic principles of strategy that can help to eliminate these reasons will be described.

In order to execute this strategy the following will be shown: the full hierarchy of the car and its components in a connection and interaction with each other; how accelerated environmental testing can be improved if a simultaneous combination of basic environmental factors (temperature, humidity, pollution, radiation, etc.) will be used; how each of these factors can be simulated more accurately in the laboratory; how one can improve accelerated corrosion testing of the car components if one takes into account that it is a combination of chemical, mechanical, motion, etc. influences; how one can improve vibration testing if one takes into account that the car's vibration is complicated and acts simultaneously with the rotation of the wheels; etc.
