摘　　要：论述直升机粘弹性阻尼器疲劳定寿的一种新方法。该方法通过损伤等效的原理将初始载荷级数较多的载荷谱等效成较为简洁的等效载荷谱,优化试验加载,同时缩短试验周期,大大提高了效率。A new method this was paper. With the damag was proposed about the fatigue life of helicopter viscoelastic damper in e equivalent conception, the initial load spectra, with many load series, then presented to simple load spectra. The cycle time of the test was shorted, and the test efficiency was improved.
