为评估弹性支承高周疲劳性能，根据某航空发动机串联式鼠笼弹性支承系统结构，设计了一套弹性支座疲劳试验件和试验参数测试方法，对弹性支座的高周疲劳性能进行试验研究。经试验验证，所设计的试验方案可以更好地模拟发动机工作状态下弹性支座的受力状态，试验过程中的载荷调节和控制更直接、便捷，为发动机弹性支承的疲劳寿命设计提供了方法支持。

To evaluate the high cycle fatigue performance of elastic support, a set of test specimen and ex-periment method have been designed based on the structure of elastic support system with multiple squirrel cages on an aero-engine. The testing results show that simulated rotor can better simulate the true stress with elastic support. The load adjustment and control during the test are more direct and convenient which provide support for fatigue life design of elastic support.
