摘　　要：加速系数是加速试验的一个关键参数,如何确定综合环境应力的加速系数是工程应用的难题。研究提出了一种基于故障模式分类,并通过对单应力加速系数进行综合,来获得综合应力加速试验加速系数的方法,从而为电子设备综合环境应力加速试验的开展提供了一种有效途径。工程实例表明,该方法合理可行。The acceleration factor is one key parameter of acceleration testing.It is difficult to determine the acceleration factor of combined environment stress.Based on failure mode classification,this paper introduces a method to determine the acceleration factor of combined environment stress by combining the acceleration factor of single stresses.This method provides an effective way to combined environment stress acceleration testing for electronic equipment.The engineering example shows that this method is reasonable and feasible.
