摘　　要：针对车用电子喇叭产品在质量改进中的可靠性特征数据难于获取问题,采用加速寿命试验方法缩短试验时间,达到快速获取失效时间数据的目的。本文通过实例,对应用背景、加速寿命试验条件、样本选取及数据处理进行了分析和说明。同时,针对车用电子喇叭产品的特殊性,试验中不仅采用了提高工作电压的加速失效方法,同时采用了包括机械结构变更、工作方式调整在内的其它加速失效方法。Accelerated life testing is used here to get the data of failure time rapidly and to solve the problem that it is difficult to get the data of reliability character.An actual example is shown to analyze and explain the processes which include the background of application,conditions for accelerated life testing,samples and analysis for data.At the same time,according to the specificity of electrical automotive horn,different means are used to reduce the failure time,not only include increased voltage,but also include the changing for the structure of samples and the adjusting for the way of horn＇s work.
