摘要
加速可靠性增长试验是可靠性试验新的研究方向和应用领域,对于可靠性要求高、任务时间长、产品子样少或价格昂贵的航天产品的可靠性增长和评价工作有良好的实施效果。对加速可靠性增长试验技术的基本原理、应用和实施的必要性、加速应力选取方法和注意事项进行了阐述,结合某型伺服系统加速可靠性增长试验方案设计实例,对传统可靠性增长试验方案和加速可靠性增长试验方案进行了比较,为加速可靠性试验技术在伺服系统后续工程研制中的应用提供了研究思路和经验借鉴。
Accelerated reliability growth test is the new research and application fields of reliability test,which brings good effect on reliability growth and evaluation of the product with high reliability,few samples or high cost.With respect to the accelerated reliability growth test technology,its basic principle,concepts,application,choosing methods of accelerated stress,and notices were introduced.Further,based on accelerated reliability growth test of a certain type of servo system,the comparison was made between accelerated reliability growth test and traditional one.The purpose was to reference for the application of accelerated reliability growth technology on later engineering development.
