中文摘要:介绍了加速寿命试验的相关理论,研究一种燃烧焊条贮存寿命预测方法。在不改变燃烧焊条失效机理的前提下,通过提高应力水平,在很短时间内得到焊条的失效数据。经过数字处理,预测出产品的贮存寿命为22年。
英文摘要:The relevant theories of accelerated life test were explained, and a method for predicting storage life of combustion welding rod was investigated. By raising stress level in the condition of unchanging failure mechanism of combustion welding rod, failure data was acquired in very short time. The estimated storage life is 22 years.
