Research on Reliability Accelerated Test Technique
To better understand and utilize the reliability accelerated test techniques,the reliability accelerated test techniques such as accelerated life test(ALT),accelerated degradation test(ADT),accelerated reliability growth test(ARGT),highly accelerated life test(HALT),and highly accelerated stress screening(HASS)are investigated by means of literature research.The applicable stages of different types of reliability accelerated test techniques in the whole life cycle of products and their application characteristics are described,and the reliability accelerated test is compared with the traditional reliability simulation test techniques.The comparison results show that the reliability accelerated test technique has been developed as a new way of product life and reliability assessment,which provides an effective method for the reliability assessment of high-reliability,small sub-sample,long-life,and zero-failure products,and solves the problem that the traditional reliability simulation test technique is difficult to expose the defects and weaknesses of product design.It points out the application prospect of reliability accelerated test technique and the future direction.This research is conducive to enhance the in-depth understanding of accelerated reliability test technique,and improve the long-term development of this technique.
