Why We Have Problems with Effective Reliability Testing Performance?

Many engineers and managers use the words “reliability testing”, fewer people think that they provide reliability testing, but often, in fact, neither of them do it. The basic reason is: none of them understands clearly what this type of testing means and how it is different from other type of testing. The literature and practice show that professionals who use vibration testing, or thermal shock testing, or environmental testing, or HALT (HASS) [22], or other types of testing think that they provide reliability testing. Companies from a wide range of industries, both in specialization and size make this error. This paper analyzes why often the knowledge of reliability testing is so poor. As a result, the process of reliability development and improvement is often slower than it might be.

Why Separate Simulation of Input Influences for Accelerated Reliability and Durability Testing is Not Effective?

This paper considers the situation in the laboratory testing: different stress types and accelerated testing, including accelerated reliability/durability testing, accelerated life testing, reliability testing, proving grounds, vibration, temperature, voltage, humidity, and others. In comparison with field situation, most of these testing simulate only one or part of the field input influences. One uses often not accurately the theory of physics-of-degradation process or failures for comparison of the field results with laboratory results. This situation will be considered with practical examples. It will be demonstrated that often used laboratory testing does not offer the possibility for successful prediction of product performance during service life As a result, there are many complaints, recalls, and less profit than was predicted during design and manufacturing. It will be shown how one can improve this situation..

This paper reviews the basic negative trends in development of real-world simulation, accelerated testing, and efficiency prediction, including: - Testing in mobile engineering and negative factors leading to the slow improvement testing, especially reliability and durability testing - Trends in using physical & virtual technology of simulation attempting to field conditions - How this influence on inaccurate prediction of product quality, reliability durability, and other components of efficiency - How current vibration and corrosion simulation differ from real-world vibration & corrosion - Trends in increasing usage of virtual simulation and decreasing physical simulation - Negative aspects of trends in publications of testing autonomous vehicles without drivers.

The Strategy of Accelerated Reliability Testing Development for Car Components

2000-03-06

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.
