Accelerated Reliability Testing of Combat Vehicles Electronic Parts Based on Multifactor Stress

Popis výsledku v původním jazyce

Electronic elements are increasingly used in a variety of applications, including in civilian and military vehicles. Evaluating the lifetime of these elements helps to control the reliability of the devices using them. With the development of manufacturing technology, electronic elements become products with high reliability and long service life. Hence the Accelerated Test is used to evaluate their reliability, reduces the time and cost of testing them. The paper is focused on reliability prediction in the case of electronic parts of combat vehicles using accelerated reliability testing. An extensive experiment has been realized to predict the reliability/life of miscellaneous electronic parts used in the design of a combat vehicle with various stress factors. As an example of the tests realized the paper presents the procedure and results of LEDs accelerated testing based on multifactor stress of the LEDs. Three types of accelerating factors have been applied – high temperature, ON/OFF cycling, and loading current. The paper deals with the methodology of the realized accelerated tests and demonstrates the procedure of test results evaluation. Two methods are used for accelerated tests data evaluation – application of the Wiener process-based model, and classical approach based on international standard IEC 60605-4. The paper compares the results of both approaches and presents selected outputs of the supposed method of the LEDs reliability prediction for various operating conditions.
