This paper provides the author’s analysis of accelerated testing development. It considers four basic directions related to this development, specifically: 1) field accelerated testing; 2) laboratory testing using computer (software) simulation; 3) laboratory or proving ground testing with physical simulation of high stress inputs; 4) accelerated reliability/durability testing (ART/ADT) as a necessary component of a system that leads to successful prediction of product efficiency.

This paper analyzes the current approaches and problems in the development of accelerated reliability testing (ART) of vehicles (components and completed product) and why in the practice ART or AT results often differ from field results. It also includes an introduction to the basic concepts of accurate ART technology: accurate simulation of all real life input influences which cause failures, simultaneously and in a combination; reproduction of the complete range of field schedules and maintenance, the proportion of heavy and light loads; not included in the test program is idle time and time with minimum loading; take into account the cumulative reaction of the product on the input influences; simulation of interconnections both between different field input influences and between components of whole machines, etc. It can be the best results of testing during the design process, but during manufacturing the reliability of a product can decrease.

This paper analyses the current approaches in the development of accelerated stress testing, and describes why present test equipment cannot provide the simulation of simultaneous combination of basic field influences on the car and car's components. The authors show a new perspective for the evalution of equipment development for accelerated testing (AT) which would eliminate the above negative aspect and solve the problem of accurate simulation of real life input influences on the natural product for its reliability improvement.

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 demonstrates the results of the analysis of the current practical situation in product reliability and durability as well as accelerated stress testing development. High stress testing is now the basic source for obtaining initial information to provide a prediction of a product's reliability and durability. This paper shows that this testing cannot offer information for the accurate prediction of reliability and durability, because the product degradation process during the testing differs from the product degradation process during the actual field situation. As a result, the time to failures also differs.

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.

This paper will discuss the problem of current trends in development accelerated testing. It will consider advantages (positive aspects) and disadvantage (negative aspects) of used accelerated testing. The author will detail the problems, using examples from SAE World Congresses, ASQ World Congresses (International Conferences), Reliability and Maintainability Symposiums (RAMS), and other world level meetings traditional approaches of accelerated testing, including ALT, HALT, HAAS, AA, and other were used. Using these traditional approaches leads to decreasing reliability, durability, and other performance components in real world. It will demonstrate that the basic reason of this situation is inaccurate simulation (physical and virtual) of real world conditions and product for different types of accelerated testing. Finally, the author will demonstrate how one could overcome this obstacle for improving accelerated testing.

The ability to successfully predict industrial product performance during service life provides benefits for producers and users. This book addresses methods to improve product quality, reliability, and durability during the product life cycle, along with methods to avoid costs that can negatively impact profitability plans. The methods presented can be applied to reducing risk in the research and design processes and integration with manufacturing methods to successfully predict product performance. This approach incorporates components that are based on simulations in the laboratory. The results are combined with in-field testing to determine degradation parameters. These approaches result in improvements to product quality, performance, safety, profitability, and customer satisfaction.

This paper reviews the current situation in the development of accelerated testing of automotive engineering, consisting of the four following areas: 1. Field testing of the natural product. 2. Additional technology of separate testing in the laboratory on the basis of physical simulation of separate field conditions using corresponding methods and equipment separately and conducting: safety testing, special programs of testing using digital simulation, special testing with changing certain parameters of environment, corrosion testing, etc. Both of the traditional testing developments above can be found in many magazines, journals, conferences, presentations, and proceedings. 3. Testing on the basis of digital (computer) simulation of product and/or field conditions. This area of testing has been developed in the last dozen years. Many articles and presentations were published during this time. 4.
