加速寿命试验是在研制过程中,对苦干件(10件或10以上)样机试制或小批试制的原型机产品进行的试验,目的是暴露设计上的差错。这种试验是一种发现设计阶段难以发觉的差错的极优越的方法。通常的做法是对产品施加稍为超过其正常工作时所承受的外部应力(热的、电的、机械的)这种应力将会暴露出薄弱的部位。然后对所观察到的失效进行分析,并采取改正措施,以减少重复发生的可能性。 Accelerated life test is a prototype test of a prototype or small batch prototype of a hard work piece (10 or more) during the development process to expose design errors. This kind of test is an extremely superior way of discovering errors that are hard to detect during the design phase. It is common practice that stress applied to the product slightly more than its normal work (thermal, electrical, mechanical) will expose weak points. The observed failures are then analyzed and corrective actions taken to reduce the likelihood of recurrence.
