| 摘 要： | 分析了牛津型斯特林制冷机的主要失效模式和失效机理，针对蓄冷器污染的失效模式提出了高温工作加速寿命评价方法。对典型牛津型制冷机进行了不同温度下的动力学响应试验，确定了适合的加速寿命试验的应力条件。加速寿命试验已进行1200h，样机性能出现了退化。样机工作参数的走势显示，退化呈现由污染所致的典型特征，初步验证了高温工作加速污染退化的可行性。

| Abstract: | Based on analysis of the main failure modes of Oxford type Stirling cooler, an accelerated lifetime evaluation technique of high temperature is developed. For a typical cooler, a series of dynamics response tests under different temperature are developed, and suitable temperature for accelerated lifetime test is gained. After 1200 hours test, the cooler presents certain degradations which is caused by contamination of regenerator. |
