The invention discloses a large paddle fatigue test device. The device comprises two bending moment applying assemblies, two movable hinge support assemblies, two centrifugal force applying assemblies and a test piece, the two bending moment applying assemblies are fixedly clamped on the test piece and are arranged along the spanwise direction of the test piece; each bending moment applying assembly is provided with a waving bending moment connector used for applying a waving bending moment in the waving direction and is provided with a shimmy bending moment connector used for applying a shimmy bending moment in the shimmy direction. The two ends of the test piece are fixedly connected with the inner ends of the movable hinge support assemblies respectively, the outer ends of the two movable hinge support assemblies are connected with the centrifugal force applying assemblies respectively, and the ends, away from the test piece, of the centrifugal force applying assemblies are fixedly connected with centrifugal force connectors used for applying centrifugal force. The large paddle fatigue test device is used for simultaneously applying a flapping bending moment and a shimmy bending moment through two bending moment applying assemblies clamped on a test piece. By adopting the fatigue test device, independent application of centrifugal force, waving bending moment and shimmy bending moment can be realized at the same time, and the requirement of a large paddle fatigue test is met.
本发明公开一种大型桨叶疲劳试验装置,该装置包括:两个弯矩施加组件、两个移动铰支组件,两个离心力施加组件以及试验件;两个弯矩施加组件固定夹持在试验件上,且沿试验件的展向布置;每个弯矩施加组件在挥舞方向上设置有用于施加挥舞弯矩的挥舞弯矩接头,在摆振方向上设置有用于施加摆振弯矩的摆振弯矩接头;试验件的两端分别与一个移动铰支组件的内端固定连接,两个移动铰支组件的外端分别连接离心力施加组件,且离心力施加组件远离试验件的一端固定连接有用于施加离心力的离心力接头;该大型桨叶疲劳试验装置,用于通过夹持在试验件上的两个弯矩施加组件同时施加挥舞弯矩和摆振弯矩。采用该疲劳试验装置能同时实现离心力、挥舞弯矩和摆振弯矩的独立施加,满足了大型桨叶疲劳试验的要求。
