| 摘 要： | 在损伤等效和失效模式相同的前提下，应用疲劳分析软件 Glyphworks，对从试验场采集的汽车排气系统道路载荷谱进行编辑。得到预计试验时间和保留不同损伤量的台架试验加速载荷谱编辑结果，并进行试验验证。结果表明：与传统耐久试验方法相比，该方法能在更短的时间内准确再现失效模式。

| Abstract: | On the premise of the same failure mode and damage equivalence,the loading spectra of the exhaust system of a passenger car were edited by using fatigue strength analysis software Glyphworks. Then both the test duration and fatigue editing were displayed with various damage retained,and validation test was conducted. Compared with traditional durability tests,the test duration and cost of our method were reduced markedly. |
