Reliability Prediction ofElectronic Devices for Combat Vehicles Based on Accelerated Testing

The wide application of highly sophisticated electronic components in combat vehicles is a key trend in recent time. Transmission systems (including engines and automatic transmissions), weapons, security, reconnaissance, and communication systems based on digital technology and have been implemented in combat vehicles. Due to the increasing number of electronic devices in combat vehicles, it can be said that this is the process of digitizing military technology. Electronic devices experience vibration stress while combat vehicle operates in a ground space. Vibration may cause structural collapse, mechanical failure, fracture, cracking, physical breakdown of the seal, complete disconnection, or interruption of electronic parts. In order to ensure the reliability of electronic devices during operation, it is necessary to conduct vibration tests for a functionally test under severe vibration environments. The presented study has applied accelerated reliability testing methods for predicting the reliability of electronic devices built in combat vehicles. A special test system has been designed to practically realize pertinent accelerated tests. The system consists of a platform base for placing electronic devices, hydraulic equipment to vibrate the base, hydraulic control system and instrumentation of system performance. The paper presents methodology of the realized accelerated tests and demonstrates procedure of tests results evaluation. Selected results of electronic devices reliability prediction based on test data are also presented. © ESREL 2021. Published by Research Publishing, Singapore.
