摘要
为了更好地理解和运用可靠性加速试验技术,通过文献调研的方式,对加速寿命试验(ALT)、加速退化试验(ADT)、加速可靠性增长试验(ARGT)、高加速寿命试验(HALT)以及高加速应力筛选(HASS)等可靠性加速试验技术进行了研究。阐述了不同类型的可靠性加速试验技术在产品全生命周期内的适用阶段及其应用特点,并将可靠性加速试验与传统可靠性模拟试验技术进行了对比。对比结果表明,可靠性加速试验技术已经发展为产品寿命与可靠性评估的新途径,为高可靠性、小子样、长寿命、零失效产品的可靠性评估提供了有效方法,解决了传统可靠性模拟试验技术难以暴露产品设计缺陷和薄弱环节的问题。指出可靠性加速试验技术的应用前景以及未来方向。该研究有利于加强对可靠性加速试验技术的深入理解,以及推进该技术的长久发展。
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.
